Question

An aqueous solution of HCl with pH 1.0 is diluted by adding equal volume of water (ignoring of water). The pH of HCl solution would (Given log 2 = 0.30)

(A) increase to 2
(B) reduce to 0.5
(C) remain same
(D) increase to 1.3

Prashant Kotian · Accepted Answer

Correct answer: D. HCl(aq) pH = 1; [H+] = 10–1 If equal volume of water is added concentration will become half. [H+]sol. = 10 1 – pH = 1.3
