Test 2 #6b

Postby Jeremiah Samaniego 2C » Tue Mar 13, 2018 1:58 pm

The following redox couple forms a galvanic cell which generates a current under standard conditions.

Pt2+/Pt and AgF/Ag,F-

b) Identify the reducing agent.

For this problem I put down AgF as the reducing agent, but the correct answer was Ag. Why is Ag the reducing agent and AgF not?

The reducing agent is the species that loses an electron. Ag goes from a neutral state to an oxidation state of +1. AgF stays neutral so this would mean Ag has to be the reducing agent.

The Ag in AgF has a charge of +1, and it goes to Ag, whose charge is 0. Therefore it gains an electron (reduction) so AgF would be an oxidizing agent.
