Ks?p of AgCl is 1�10?10. Its solubility in 0.1MKNO3? will be : (1) 10-5 moles/litre(2) >10-5 moles/litre (3) <10-5 moles/litre (4) None of the above

Answer: (1)

Consider a reaction

AgCl_(s) → Ag⁺_(aq)+ Cl^–_(aq)

K_SP = [Ag⁺][Cl^–]/[AgCl]

K_SP = s² = 1×10^-10

s = 10^-5

KNO₃ →K⁺+NO₃⁻

Since there is no common ions in the addition of nitric acid. Therefore it has no effect on the overall solubility of the AgCl.

∴ Solubility = 10^-5
