## The copper(I) ion forms a chloride salt that has Ksp = 1.2 × 10−6. Copper(I) also forms a complex ion with Cl−: Cu + ( a q )   +   2 C l − ( a q )   ⇌   C u C l 2 − ( a q )   K   =   8.7   ×   10 4 a. Calculate the solubility of copper(I) chloride in pure water. (Ignore CuCl2− formation for part a.)b. Calculate the solubility of copper(I) chloride in 0.10 M NaCl.

(a)

Interpretation Introduction

Interpretation: The solubility of the given compound is to be calculated.

Concept introduction: Solubility is defined as the maximum amount of solute that can dissolve at a certain amount of solvent at certain temperature. The solubility product, Ksp is the equilibrium constant that is applied when salt partially dissolve in a solvent. The solubility product of dissociation of AxBy is calculated by the formula,

Ksp=[A]x[B]y

### Explanation of Solution

Explanation

To determine: The molar solubility of CuCl in pure water.

The molar solubility of CuCl in pure water is 0.0011M_ .

Given

The Ksp of AgI is 1.2×106 .

The dissociation reaction of CuCl is,

CuClCu++Cl

The solubility of Cu+ is assumed to be smol/L .

The solubility product of dissociation of CuCl is calculated by the formula,

Ksp=[Cu+][Cl]

The solubility of CuCl can be calculated from the concentration of its ions at equilibrium.

It is assumed that smol/L of solid is dissolved to reach the equilibrium
