Product Details

Acids are acidic, bases are basic, and salts are neutral—right? Not exactly! Teach your students that certain salts dissolve in water to produce acid solutions and others produce basic solutions with this colorful lab. Using universal indicator in test tubes, your students will discover colorful solutions from the simple hydrolysis of salts. Students write and discuss the hydrolysis reactions for five different salts with water. Teacher notes and reproducible student handouts include easy-to-follow lab instructions, sample data, answers to questions and in-depth background information.

Super Value Kit is complete for 5 classes of 30 students working in pairs.

Performance Expectations

MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
