Question

37. \( 8 \times 10^{-6} M AgNO \), solution is gradually added in \( 1 L \) of \( 10^{-4} M KCl \) solution. Upto what volume of \( AgNO _{3} \) solution being added (in \( L \) ), precipitation of \( AgCl \) will not take place? \( \left( K _{ pp }\right. \) of \( \left.AgCl =2 \times 10^{-10}\right) \)

Answer 1

AgNO₃ + KCl → AgCl + KNO₃

KSP = 2 x 10^-10

S² = 2 x 10^-10

S = √2 x 10^-5

M₁V₂ + M₂V₂ = M₃ x V_f

8 x 10^-4 x V + 1 x 10^-4 = √2 x 10^-5(1 + V)

10^-4 (8V + 1) = 1.4 x 10^-5 + 1.4 x 10^-5V
