Acids and Bases

In each of the following equations, identify the reactant that is a Brønsted-Lowry acid and the reactant that is a Brønsted-Lowry base:

a. HBr(aq)+H_{2} O(l) \longrightarrow Br^{-}(aq)+H_{3} O^{+}(aq)

b. CN^{-}(aq)+H_{2} O(l) \rightleftarrows HCN(aq)+OH^{-}(aq)

The blue check mark means that this solution has been answered and checked by an expert. This guarantees that the final answer is accurate.
