Which of the following salts will give highest pH in water
Options
(a) KCl
(b) NaCl
(c) Na₂CO₃
(d) CuSO₄
Correct Answer:
Na₂CO₃
Explanation:
Na₂CO₃ is a salt of strong base (NaOH) and weak acid (H₂CO₃). On hydrolysis this salt will produce strongly basic solution. i.e pH will be highest (pH>7) for this solution. Others are combination of
KCl= strong acid +strong base →neutral solution (pH≈7)
Nacl= strong acid +strong base →neutral solution (pH≈7)
CuSO₄= strong acid + weak base → Acidic solution (pH<7)
