Stoichio-What?? Chemistry January +

Stoichio-WHAT? Objectives To determine the mass of copper formed in a reaction. To use this information to decide the identity of one of the products.

Stoichio-WHAT? Procedure

Stoichio-WHAT? Results Data Mass of copper(II) sulfate Mass of iron Mass of copper (product) Record Observations From your observations, make a prediction of which iron-containing product will occur.

Stoichio-WHAT? Conclusions 1. Which reactant was limiting? What observations support this? Use the chemical equation for the reaction that occurred in this lab and stoichiometric calculations to support your answer. 2. What is the formula for the iron-containing compound that is formed when copper(II) sulfate and iron react? How do you know? 3. Calculate percent yield of copper.
