Quizplus · Accepted Answer

Sodium sulfate (Na2SO4) dissociates into 2 Na+ ions and 1 SO4^2- ion. Therefore, the concentration of sodium ions is twice that of the sulfate ions. For a 2.104 M solution of Na2SO4, the concentration of Na+ is 2 * 2.104 M = 4.208 M, and the concentration of SO4^2- is 2.104 M.
