Synthesis of a Coordination
Compound—Student Laboratory Kit
By: The Flinn Staff
Some of the most colorful and interesting compounds to study in chem- istry are the coordination compounds. These compounds are usually salts that contain a complex ion; that is, a metal atom bonded to small polar anions, or ligands. In this two-part lab, students will synthesize the brilliant green coordination compound potassium trioxalatoferrate(III) trihydrate, K3[Fe(C2O4)3]•3H2O. In Part 1, the students prepare an inter- mediate product, iron(II) oxalate. This solid is then converted in Part 2 to potassium trioxalatoferrate(III) trihydrate by oxidation with hydrogen peroxide in the presence of potassium oxalate. The final product is filtered, dried, and weighed. Students use the data to calculate the percent yield. Includes reproducible student procedure, complete Instructor’s Notes with sample data and answers to questions, and all necessary chemicals.
Complete for 24 students working in pairs.

What Is a Chemical Reaction?
Student Laboratory Kit
By: The Flinn Staff
Chemical change is a central part of our modern world. Although it is responsible for most of the energy, materials and medicines that we depend on in our daily lives, chemical change may be mostly invisible to students. What is a chemical change? How can students identify a chemical change? In this microscale experiment, students study the properties of hydrochloric acid and copper(II) chloride with a variety of substances to observe and identify signs of chemical change. As students gather evidence in this introductory-level experiment, they begin to discover similarities, differences and patterns in the chemical properties of matter. Includes reproducible student handouts, detailed background information, complete Instructor’s Notes with sample data and answers to questions and all necessary chemicals and consumable supplies.
Complete for 30 students working in pairs. Fifteen reusable, 24-well reaction plates are recommended and available separately.

Qualitative Analysis—Guided-Inquiry Kit
By: The Flinn Staff
Lab isn’t just about “getting the right answer,”
although that’s what your students may tell you. Learning how to design an experiment, based on scientific principles and logical reasoning, is often overlooked when students have to follow rigid procedures. Use this guided-inquiry activity to refocus your students and help them develop good critical-thinking skills. The purpose of this inquiry-based lab is for students to design and carry out a sequence of chemical reactions to separate and identify iron(III), zinc, and silver ions in water. Includes comprehensive instructor notes with sample data and answers to all questions. This student-directed activity is a great review of chemical reactions!
Complete for 30 students working in pairs.
