Product Details

Stoichiometry—what a strange and scary word! Teach students about mole ratios and take the fear out of stoichiometry calculations with this student lab activity. The reaction of copper wire with silver nitrate in aqueous solution shows chemistry in action. Silver crystals grow on the wire surface, and the color of copper(II) ions appears in solution. Students measure the mass of the silver produced, determine the mass of copper wire that reacted and calculate the number of moles of each. After comparing the number of moles of reactants versus products, students determine the mole ratio and write the balanced chemical equation for the reaction. When students first see the beautiful silver crystals in this reaction, many think they can get rich quick. Stoichiometry teaches them otherwise! Includes reproducible student handouts, detailed background information, complete Teacher Notes with sample data and answers to questions and all chemicals needed to perform the lab.

Complete for 30 students working in pairs.
