A compound that produces hydroxide ions in solution is what type of substance?

A compound that produces hydroxide ions in solution is a base. When such a substance dissolves, it increases the concentration of OH− ions, which raises the pH and makes the solution basic. This is the Arrhenius view of bases. In contrast, acids release hydrogen ions (H+) or hydronium (H3O+) in solution, lowering the pH. Salts formed from neutralization typically don’t inherently generate hydroxide ions, though some may affect pH through hydrolysis. Common bases include sodium hydroxide and calcium hydroxide, which directly supply OH− in water. In practical terms, a substance that creates hydroxide ions in solution is used to raise pH, so it fits the description of a base.
