Limiting Reagent Lab
Background: In this lab, we will perform a reaction between 2 grams tron filings and 7 grams of
copper (II) sulfate solution that produces copper metal and iron (Il) sulfate, Iron fitings are brown
in color and have a coarse texture. Copper (I) sulfate is a white powder, when mtxed with a water
it will turn into a blue solution.
Purpose: To determine which chemical runs out and stops the reaction (which is the limiting
reagent) the brown iron filings, or the blue copper (II) sulfate solution. Additionaly, this lab will
demonstrate the accuracy of calculating the theoretical yield of copper.
Pre Lab Questions: Perform the calculations necessary to determine the timiting reagent, excess
reagent and theoretical yield. Show.all work in order to receive tull credit.
A. Limiting reagent and Excess reagent
a. Step 1: Balance Equation . Fe + _ CusO, -» _ Cu + Fe,(SO,),
b. Step 2: Find molar ratio between Fe and Cuso,
C. Step 3: Convert grams to moles for both Fe and Cuso
d. Step 4: Compare molar ratio and actual moles
B. Theoretical Yleld of copper(Cu)
a. Convert moles of limiting reagent to moles of copper (Cu)
b. Convert moles of copper (Cu) to grams of copper (Hint: use molar mass of copper)
Hypothesis: Based on your prelab calculations, which reagent will run out and stop the reaction
(Umiting reagent) and which reagent will be leftover? How much copper will be produced?
