Question

Which has the highest pH? (A) CH3COOK (B) Na2CO3 (C) NH4Cl (D) NaNO3

Tardigrade Admin · Accepted Answer

NH4Cl solution is acidic, its pH < 7. NaNO3 solution is neutral, its pH = 7. CH3COOK and Na2CO3 solutions are basic their pH > 7. But Na2CO3 solution is more basic, its pH > pH of CH3COOK solution.
