Gravimetric Analysis of a Metal Carbonate

Determining the identity of a compound through gravimetric means is an experiment that ties together principles and concepts from several “big ideas” in chemistry, including stoichiometry, chemical reactions and solubility. Gravimetric analysis emphasizes science practice skills involving mathematical reasoning and data analysis.

pH Properties of Buffer Solutions Inquiry Guidance & AP* Chem Curriculum Alignment Transition Guide

The physiological role of buffers within cells and in consumer products highlights the ability of buffers to resist changes in pH. Buffers provide an essential acid−base balancing act—in foods and drugs, consumer products, lakes and streams, and even living cells. All biological cells depend on the properties of buffers, as does the essential function of the respiratory system, breathing, which must be regulated within a very narrow pH range. What are buffers made of and how do they work?

Electrochemical Cells Inquiry Guidance and AP* Chemistry Curriculum Alignment Transition Guide

Explore the fundamental role of electron transfer in oxidation and reduction reactions by studying the voltage of galvanic cells. What are the basic features of an electrochemical cell? How can reduction potentials be measured? What factors determine the ability of a galvanic cell to produce electricity? How does the voltage of a galvanic cell depend on concentration? Can this relationship be used to determine the solubility constant for a salt?

An Activity Series Inquiry Guidance and AP* Chemistry Curriculum Alignment Transition Guide

The elements are classified based on similarities, differences, and trends in their properties. Recognizing periodic trends in the physical and chemical properties of the elements is key to understanding the full value of the periodic table. Which elements more easily undergo oxidation by giving up electrons? What factors determine the ease of reduction of elements or ions? How does the relative reactivity of a group of metals or nonmetals influence their uses in commerce, engineering or medicine? Investigate these questions to reinforce key learning objectives concerning oxidation and reduction.

Synthesis & Purification of an Ester Inquiry Guidance/AP* Chem Curriculum Alignment Transition Guide

The study of organic chemistry is organized around functional groups—groups of atoms bonded together in a specific pattern that give organic compounds their unique physical and chemical properties. The ester functional group is widely distributed in nature. Low molecular weight esters are responsible for the pleasant odor or fragrance of many fruits and flowers, and are thus important ingredients in natural and artificial flavors. Ethyl acetate is a simple ester that is used as a flavor aid for pharmaceuticals and artificial fruit essences.

Reaction Enthalpy & Hess’s Law Inquiry Guide & AP* Chemistry Curriculum Alignment Transition Guide

The heat or enthalpy change for a chemical reaction is called the enthalpy of reaction. This energy change is equal to the amount of heat transferred, at constant pressure, in the reaction. The enthalpy of a reaction represents the difference in enthalpy of the products and the reactants and is independent of the steps in going from reactants to products. According to Hess’s law, if a reaction can be carried out in a series of steps, the sum of the enthalpies for each step equals the enthalpy change for the overall reaction.

Determine Keq for FeSCN2+ Inquiry Guidance and AP* Chemistry Curriculum Alignment Transition Guide

The equilibrium constant gets its name from the fact that for any reversible chemical reaction, the value of Keq is a constant at a particular temperature. The concentrations of reactants and products at equilibrium will vary, depending on the initial amounts of materials present. The special ratio of reactants and products described by the equilibrium constant is always the same, however, as long as the system has reached equilibrium and the temperature does not change. The equilibrium constant can be calculated if the concentrations of reactants and products at equilibrium are known.

Synthesis of a Coordination Compound Inquiry Guidance/AP* Chem Curriculum Alignment Transition Guide

Coordination compounds are interesting substances. They are usually highly colored and produce beautiful crystals. In this lab, green crystals of the coordination compound potassium trioxalatoferrate(III) trihydrate will be synthesized. The crystals are then analyzed to determine their identity, purity and the percent yield of the product.

Liquid Chromatography Inquiry Guidance and AP* Chemistry Curriculum Alignment Transition Guide

Chromatography is an important analytical tool used to separate the components of a mixture.

Determination of Cations & Anions Inquiry Guidance & AP* Chem Curriculum Alignment Transition Guide

Much of laboratory chemistry is focused on the question of how much of a given substance is contained in a sample. Sometimes, however, the focus shifts to what substances are in the sample, rather than their quantity. The purpose of qualitative analysis is to identify a series of either cations or anions in a solution through a sequence of chemical reactions and separation procedures.

Molar Mass: Gases & Volatile Liquids Inquiry Guidance/AP* Chem Curriculum Alignment Transition Guide

Students will gain further understanding of the gas laws when applied to determine the molar mass of gases and volatile liquids. Amazing how two distinct concepts can be tied together in this advanced laboratory! The molar mass of a compound is an intrinsic property of a substance that is required for all chemical reactions and analyses. How is molar mass verified and how can the molar mass of an unknown be determined?

Freezing Point Depression Inquiry Guidance & AP* Chemistry Curriculum Alignment Transition Guide

The freezing point depression and other colligative properties of a solution were traditionally used to determine the molar mass of a solute. While this method has been superseded by modern instrumental methods for molar mass determination, it remains an interesting experiment for understanding the physical basis of the freezing point, and also for its applications to daily life.

Analyze Aluminum Potassium Sulfate Inquiry Guidance & AP* Chem Curriculum Alignment Transition Guide

Synthesized compounds often undergo a series of characterization techniques or tests to confirm the chemical structure and properties of that particular compound. There are a number of tests that can be performed to verify the identity of a compound. In this experiment, several tests are carried out to determine if sample crystals are aluminum potassium sulfate (alum).

Empirical Formula of Silver Oxide Inquiry Guidance & AP* Chem Curriculum Alignment Transition Guide

Determining the empirical formula of a substance is a classic experiment in AP chemistry to analyze the composition of chemical compounds. This is not an abstract problem, since more than 20 million different inorganic and organic compounds have been synthesized. Twenty million compounds—how is it possible to identify so many different compounds and tell them all apart?

Acid–Base Titrations Inquiry Guidance and AP* Chemistry Curriculum Alignment Transition Guide

Acid–base titrations are excellent methods for students to design their own experiments and start thinking quantitatively in the lab! A common question chemists have to answer is how much of something is present in a sample or a product. If the product contains an acid or base, this question is usually answered by a titration. Acid–base titrations can be used to measure the concentration of an acid or base in solution, calculate the formula or molar mass of an unknown acid or base, and determine the equilibrium constant for a weak acid (Ka) or a weak base (Kb).

Kinetics of a Reaction Inquiry Guidance and AP* Chemistry Curriculum Alignment Transition Guide

How fast will a chemical reaction occur? If a reaction is too slow, it may not be practical. If the reaction is too fast, it may explode. Measuring and controlling reaction rates makes it possible for chemists and engineers to make a variety of products, everything from antibiotics to fertilizers, in a safe and economical manner. The purpose of this experiment is to investigate how the rate of a reaction can be measured and how reaction conditions affect reaction rates.

Indicators & Acid–Base Titrations Inquiry Guidance & AP* Chem Curriculum Alignment Transition Guide

Acids and bases vary in their strength and are normally classified as strong or weak. In any acid–base titration, the neutralization, or equivalence point, occurs when the moles of acid in solution are equal to the moles of base. The pH of the solution at this point will vary widely and depends on the strength of both the acid and the base. How is an indicator selected that fits a particular acid–base titration?

Determine Ka of Weak Acids Inquiry Guidance & AP* Chemistry Curriculum Alignment Transition Guide

Acids vary greatly in their strength—their ability to ionize or produce ions when dissolved in water. What factors determine the strength of an acid? In this experiment, the strength of acids are determined by the equilibrium constants for their ionization reactions in water.

Chemical Reaction Stoichiometry Inquiry Guidance/AP* Chemistry Curriculum Alignment Transition Guide

Double replacement reactions are generally considered to be irreversible. The formation of an insoluble precipitate provides a driving force that makes the reaction proceed in one direction only. The purpose of this laboratory is to find the optimum mole ratio for the formation of a precipitate in a double replacement reaction and use this information to predict the chemical formula of the product.

Oxidation–Reduction Titrations Inquiry Guidance/AP* Chemistry Curriculum Alignment Transition Guide

Determining the amount of a particular substance in a sample or product is a common task in analytical chemistry. If the product contains a substance that can be oxidized, then it is possible to determine the number of moles of that substance by titrating the sample with a strong oxidizing agent. In this lab, an oxidizing solution will be standardized and then used to determine the number of moles of oxalic acid.
