\nIn the given reaction, HSO\u2084\u207b + H\u2082O \u2192 H\u2083O\u207a + SO\u2084\u00b2\u207b, the hydrogen sulphate ion (HSO\u2084\u207b) donates a proton (H\u207a) to water (H\u2082O). According to the Br\u00f8nsted-Lowry acid-base theory, an acid is a proton donor and a base is a proton acceptor. Since water accepts a proton from HSO\u2084\u207b to form H\u2083O\u207a, water is acting as a base in this specific reaction.

\nWater is an amphoteric substance, meaning it can act as both an acid and a base depending on the substance it reacts with. When reacting with a stronger acid (like HCl), water acts as a base. When reacting with a base (like NH\u2083), water acts as an acid. In this reaction with HSO\u2084\u207b, which can act as either an acid or a base but is acting as an acid here (donating H\u207a), water acts as a base.
