Directions:

• Print out the worksheet: Single Replacement Lab Sheet

• Use the information and pictures below to help you complete the worksheet.

Read this before completing the front side of the worksheet:

The purpose of this lab is to examine how different amounts of a reactant will affect the amount of product made in the end.

• Each lab group filled a test tube with 8 mL of copper(II) sulfate solution.

• Each group was then assigned a different amount of zinc to place into the copper(II) sulfate solution.

• The image below shows the amounts that each lab group placed into the 8 mL copper(II) sulfate solution.

• When completing the lab sheet, imagine you sat at lab station #1 toward the front of the room and added between 0.1 and 0.2 g of zinc to the 8 mL copper(II) sulfate solution.

• Below is a picture of the copper(II) sulfate solution, the zinc, and then the test tube when they are first put together.

• At this point, answer the questions on the front side of the worksheet.

We now waited 45 minutes for the reaction to take place. While waiting we worked on another worksheet. Check the calendar to see what we did while waiting for the reaction to take place.

Read this before completing the back side of the worksheet:

• The test tubes prepared by each group were put in order of least amount of zinc (Group #1) to most amount of zinc (Group #6)

• This is a picture of the six test tubes after waiting 45 minutes for them to react.

• This is a close up picture of test tube #6 to help you with question #10.

Be sure to hand this worksheet in to your teacher when you return to school.
