Question

Quizplus · Accepted Answer

Na2SO4 is sodium sulfate which is a salt of a strong base (NaOH) and a strong acid (H2SO4). When this salt dissolves in water, it dissociates into Na+ and SO4 2- ions. The Na+ ions do not react with water but the SO4 2- ions can accept a proton from water, forming the hydroxide ion (OH-), which makes the solution basic.
