The Stoichiometry group contains three groups: Exploding Soap Bubbles: Hydrogen + Oxygen; Acid-Base Titrations and Animation; and Redox Titration and Animation.
Gas Stoichiometry  
Gas is generated from one mole of liquid of solid and the volume is measured using a gas collection system.

Atoms,_Molecules_and_Ions : MassInAlloy (10 Variations)
Gold is alloyed with other metals to make it less malleable. 10 karat gold is an alloy that is 41.7% gold. How much pure gold is in a 20. gram 10 karat gold ring?
Stoichiometry : GramMoleProblem (9 Variations)
Which sample contains the largest number of nitrogen atoms?
Stoichiometry : LimitingReagent (8 Variations)
The synthesis of urea by Frederich W??hler in 1825 began the decline of the idea that "organic" chemicals could only be made by living organisms as part of their biological processes.

AgOCN(aq) + NH4Cl(aq)AgCl(s) + NH2CONH2(aq)

If you perform this reaction and collect the following table of data, in which trial(s) is AgOCN clearly the limiting reactant?

Trial AgOCN used NH4Cl AgCl produced
1 20.4 mL 5.3 mL 2.4 g
2 20.3 mL 10.4 mL 4.3 g
3 20.6 mL 15.4 mL 6.2 g
4 20.5 mL 20.6 mL 8.2 g
5 20.4 mL 25.2 mL 10.2 g
6 20.3 mL 30.4 mL 10.3 g

The mL of AgOCN and NH4Cl are the initial amounts used, the mass of AgCl is how much was recovered from the reaction. (Hint: You do not need to do any calculations to answer this question.)

The Synthesis and Analysis of Copper(I) Iodide. A First-Year Laboratory Project  Lara A. Margolis, Richard W. Schaeffer, and Claude H. Yoder
This project provides a convenient preparation of a compound whose identity will not be obvious to students. The analytical procedures illustrate the fundamentals of gravimetric analysis and some basic chemical and physical characteristics of the elements. The analytical data allow students to find the identity of the product by determining its empirical formula.

Preparation and Analysis of Multiple Hydrates of Simple Salts  Richard W. Schaeffer, Benny Chan, Shireen R. Marshall, Brian Blasiole, Neetha Khan, Kendra L. Yoder, Melissa E. Trainer, and Claude H. Yoder
A laboratory project in which students prepare a series of hydrates of simple salts and then determine the extent of hydration of the product(s); provides a good introduction to the concepts of solubility, saturation, recrystallization, relative compound stability, and simple gravimetric analysis.
