Identify the oxidation state of Ca in Ca Br₂(aq). Ca(s)+ 2H Br(aq)→ Ca Br₂(aq)+ H₂(g) A) +1 B) +2 C) 0 D) -1 E) -2

Question

Quizplus · Accepted Answer

The oxidation state of Br, S, and H is -1, -2, and +1, respectively. Therefore, the sum of the oxidation states in Ca Br₂(aq) is -1 + (-2) + 2(+1) = 0. Since the compound is neutral, the oxidation state of Ca must be the negative sum of the other oxidation states, which is +2. Therefore, the correct answer is B.
