प्रश्न
Which of the following salts will give an aqueous solution having pH of almost 7?
(a) NH4NO3
(b) NH4Cl
(c) CaCl2
(d) KCl
उत्तर
KCl
KCl is formed from a strong acid, hydrochloric acid (HCl), and a strong base, potassium hydroxide (KOH). Thus, KCl, on hydrolysis, forms equal amounts of H+ and OH- ions. This is why an aqueous solution of KCl shows a pH of almost 7.
