WebMay 8, 2024 · A salt can dissolve in water to produce a neutral, a basic, or an acidic solution, depending on whether it contains the conjugate base of a weak acid as the anion ( A^− ), the conjugate acid of a weak base as the cation ( BH^+ ), or both. Salts that contain small, highly charged metal ions produce acidic solutions in water. WebA salt dissociates into anions and cations in an aqueous solution. The anions have a negative charge, and so, have an affinity for the H+ ions. The cations have a positive charge and have an affinity for the OH- ions.
