I'm very confused about this question, first, why did the answer have H2 on the product side? I thought H+ ions were forming on the product side, not H2 gas? It also says 'aqueous,' which means it's in water. So, wouldn't the balanced chemical equation be, K (s) + H20 (L) ----> KOH (aq) + H+ (L)? I'm confused about how they obtained the gaseous H2.
