Q.) What is the pH of the acid which is used in
the formation of common salt?
(a) Between 1 to 3
(b) Between 6 to 8
(c) Between 8 to 10
(d) Between 11 to 13
Ans. (a) Between 1 to 3
Explanation : Common salt or NaCl is formed from hydrochloric acid, HCl and sodium hydroxide, NaOH. HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l) As HCl is a strong acid, its pH will be between 1 to 3.
