Answer #1

Ans- Correct option Is b) AgCl

EXPLANATION

pH affects solubilities

A substance having basic anion ( anion of a weak acid) is more soluble in an acidic solution .

Basic anions includes:- OH-, S2- , (CO3)2-

Case 1- Solubility increases as pH decreases for Salt whose anion is conjugate base of weak acid .

Case 2 - Salts whose anion is conjugate base of strong acid, it's solubility remains unaffected by change in ph.

AgCl has conjugate base of strong acid (HCl ) so it falls in second case .
Hence correct answer is b) AgCl
