Question

Quizplus · Accepted Answer

Na2SO4 dissociates into 3 ions in water (2 Na+ ions and 1 SO4 2- ion), while both NaCl and NH4Cl dissociate into 2 ions in water (1 Na+ or NH4+ ion and 1 Cl- ion). Na2SO4 therefore produces the greatest number of ions. NH₄NO₃ does not exist. Na₂SO₄ represents disodium hydrogen phosphate, which dissociates into 3 ions in solution, similar to Na2SO4. Sucrose does not dissociate into ions in water and therefore does not produce any ions.
