The solubility of AgCl in pure water at 25 °C is \(1.33 \times 10^{-5}\ \text{mol\ L}^{-1}\). When the temperature is raised to 35 °C the solubility increases by 20 %. If 0.010\ mol\ L\(^{-1}\) NaCl is added to the solution at 25 °C, calculate the new solubility of AgCl at this temperature.

A. 2.0 \\times 10^{-8} mol L^{-1}

B. 1.5 \\times 10^{-8} mol L^{-1}

C. 1.8 \\times 10^{-7} mol L^{-1}

Correct Answer D. 1.8 \times 10^{-8} mol L^{-1}

Correct Answer

Correct Option:

1.8 \times 10^{-8} mol L^{-1}
