Use the Following Information to Calculate the Solubility Product Constant

Multiple Choice

Use the following information to calculate the solubility product constant, K_sp, for PbCl₂. A saturated solution of PbCl₂ in water was prepared and filtered. From the filtrate, 1.0 L was measured out into a beaker and evaporated to dryness. The solid PbCl₂residue recovered in the beaker amounted to 0.0162 moles.

C) K _sp = 1.7 × 10 ⁻⁵
D) K _sp = 2.6 × 10 ⁻⁴
E) K _sp = 3.2 × 10 ⁻²
