Answer & Solution

Correct Answer

(B) \(14\)

Step-by-step Solution

Detailed explanation

\({\left[ Ag ^{+}\right]=10^{-5}}\) \({\left[ NO _3^{-}\right]=10^{-5}}\) \({\left[ Br ^{-}\right]=\frac{ Ksp }{\left[ Ag ^{+}\right]}=4.9 \times 10^{-8}}\) \(\Lambda_{ m }=\frac{ k }{1000 \times M }\) For \(Ag ^{+}\)…
