Question: In the reaction 2Ag+ + Zn → 2Ag + Zn2+, what is the oxidation state of zinc after the reaction?

Options:

Correct Answer: +2

Solution:

Zinc (Zn) is oxidized to Zn2+, so its oxidation state is +2.

In the reaction 2Ag+ + Zn → 2Ag + Zn2+, what is the oxidation state of zinc after the reaction?

In the reaction 2Ag+ + Zn → 2Ag + Zn2+, what is the oxidation state of zinc after the reaction?

Step 1: Identify the reactants in the reaction, which are 2Ag+ and Zn.
Step 2: Look at the products of the reaction, which are 2Ag and Zn2+.
Step 3: Determine what happens to zinc (Zn) in the reaction. It changes to Zn2+.
Step 4: Understand that when zinc changes to Zn2+, it loses two electrons.
Step 5: Recognize that losing electrons means zinc is being oxidized.
Step 6: Know that the oxidation state of an element increases when it is oxidized.
Step 7: Since zinc goes from 0 (in elemental form) to +2 (in Zn2+), its oxidation state after the reaction is +2.
