Module 3—Electrochemical Reactions

Lesson 1 Lab: Observing the Reactivity of Zinc

 

What happens when a metal is involved in a chemical reaction?

 

View the virtual investigation “Observing the Reactivity of Zinc.” You will observe the changes that occur when zinc reacts with a solution of silver nitrate. Record your observations and answer the Analysis questions as you work through this investigation. Save a copy of your work in your course folder.

 

Analysis

  1. Write the balanced chemical equation for the reaction of zinc and aqueous silver nitrate.

  2. Indicate what empirical evidence you observed in the investigation that supports the equation you have written.

  3. Identify which substances have undergone change in this reaction? Is the change the substance(s) underwent an electrochemical change involving a transfer of electrons? Support your reasoning.

In the next activity, you will read and work through “Sample problem 13.1” in the textbook. You will be prompted to check your answers to the Analysis Questions after completing your reading.
