The solubility product of AgCl is 1.8 × 10 ^ – 10 . Precipitation...
The solubility product of is . Precipitation of will occur only when equal volumes of which of the following solutions are mixed?
Options
- A and
- B and
- C and
- D and
Correct answer
A. and
Step-by-step solution
After mixing,
\left[{Cl}^{–}\right] = \dfrac{1}{2} \times {10}^{– 4} = 5 \times {10}^{– 5}M{Q}_{\text{sp}} = \left[{\text{Ag}}^{+}\right]\left[{\text{Cl}}^{–}\right] = {\left(5 \times {10}^{– 5}\right)}^{2} = 2.5 \times {10}^{– 9}{Q}_{\text{sp}} > {K}_{\text{sp}} \to precipition takes place
\left[{Cl}^{–}\right] = \dfrac{1}{2} \times {10}^{– 4} = 5 \times {10}^{– 5}M{Q}_{\text{sp}} = \left[{\text{Ag}}^{+}\right]\left[{\text{Cl}}^{–}\right] = {\left(5 \times {10}^{– 5}\right)}^{2} = 2.5 \times {10}^{– 9}{Q}_{\text{sp}} > {K}_{\text{sp}} \to precipition takes place
