A saturated solution of AgCl at 25 °C contains \(1.3\times10^{-5}\) mol L\(^{-1}\) of \(\text{Ag}^+\). When the temperature is raised to 35 °C the solubility of AgCl increases by 40 %. The solution also contains \(5.0\times10^{-6}\) mol L\(^{-1}\) of \(\text{Cl}^-\) from NaCl. Assuming the solubility product changes only because of the temperature increase, calculate the equilibrium concentration of \(\text{Ag}^+\) at 35 °C.

Answer Options

A. 1.6×10⁻⁴ mol L⁻¹
B. 1.0×10⁻⁵ mol L⁻¹
Correct Answer C. 1.6×10⁻⁵ mol L⁻¹
D. 2.2×10⁻⁵ mol L⁻¹
Correct Answer
C
Correct Option:
1.6×10⁻⁵ mol L⁻¹
