A substance that tastes sour, reacts with metals and carbonates.

Explanation:
Acids are substances that show a sour taste and react with metals and carbonates. The sour taste is a classic property (think citric acid in lemons). When acids meet metals, they typically produce hydrogen gas; when they meet carbonates, they fizz as carbon dioxide forms. This combination of reactivity with metals and carbonates, plus the sour taste, points to an acid. Bases would usually feel slippery and taste bitter and don’t fizz with carbonates in the same way. Salts are the products of acid-base reactions and don’t inherently exhibit this set of properties, and solvents describe the dissolving medium rather than this reactive behavior.
