If you properly balance the following half reaction in base solution,how many electrons would appear on the product side of the equation?
Al (s) → Al(OH) ₄^1- (aq)

Question

Quizplus · Accepted Answer

In order to balance the half-reaction in base solution, we first need to identify the oxidation state of each element involved. Al has an oxidation state of 0 on the reactant side and an oxidation state of +3 on the product side (since it appears as part of the Al(OH)4- ion). Therefore, we can write the half-reaction as:

Al (s) → Al(OH)4- (aq) + 3 e-

In this balanced equation, there are 3 electrons on the product side. Therefore, the correct answer is B) 3.
