Answer & Solution

Correct Answer

(C) \(5\)

Step-by-step Solution

Detailed explanation

\({\left[ Ba ^{+2}\right]=\frac{25 \times 0.05}{50}=0.025 M }\) \({\left[ F ^{-}\right]=\frac{25 \times 0.02}{50}=0.01 M }\) \({\left[ Ba ^{+2}\right]\left[ F ^{-}\right]^2=25 \times 10^{-7}}\) \(K _{ sp }=5 \times 10^{-7} \text { (given) }\)…
