The solubility product of silver chloride at 25 °C is Ksp = 1.8 × 10⁻¹⁰. When 0.010 mol of NaCl is dissolved in 1.0 L of water, the solution is saturated with AgCl. (a) Calculate the solubility of AgCl (in mol L⁻¹) in this solution at 25 °C. (b) At 35 °C the Ksp of AgCl increases to 2.0 × 10⁻¹⁰. Assuming the NaCl concentration remains 0.010 M, determine the new solubility of AgCl at 35 °C.

Answer Options

A. 9.0×10⁻⁹ mol L⁻¹ at 25 °C; 1.0×10⁻⁸ mol L⁻¹ at 35 °C
B. 1.3×10⁻⁵ mol L⁻¹ at 25 °C; 1.4×10⁻⁵ mol L⁻¹ at 35 °C
C. 2.5×10⁻⁸ mol L⁻¹ at 25 °C; 2.8×10⁻⁸ mol L⁻¹ at 35 °C
Correct Answer D. 1.8×10⁻⁸ mol L⁻¹ at 25 °C; 2.0×10⁻⁸ mol L⁻¹ at 35 °C
Correct Answer
D
Correct Option:
1.8×10⁻⁸ mol L⁻¹ at 25 °C; 2.0×10⁻⁸ mol L⁻¹ at 35 °C
