Question

When equal volumes of the following solutions are mixed, precipitation of AgCl (Ksp = 1.8 x 10-10) will occur only with

(a) 10–4 M [Ag+] and 10–4M[HCl]

(b) 10–5 M[Ag+] and 10–5 M [Cl– ]

(c) 10–6M [Ag+] and 10–6 M [Cl-–]

(d) 10–10 M [Ag+] and 10–10M [Cl– ]

Answer 1

Correct option (a) 10–4M [Ag+] and 10–4M[HCl]

Explanation:

We look for that case where the ionic product exceeds the Ksp
