Chapter 8: Q5 TY (page 168)

Find $[{Hg}_{2}^{2 +}]$ in equilibrium with 0.010MKCl saturated with ${Hg}_{2} {Cl}_{2}$ .

Short Answer

Expert verified

The value of $[{Hg}_{2}^{2 +}]$ in equilibrium with 0.010M KCI saturated ${Hg}_{2} {Cl}_{2}$ is $2.2 \times 10^{- 14} M$

Step by step solution

Concept used.

Solubility product $(K_{s p})$ :

The product of a substance's dissolved ion concentrations raised to the power of their stoichiometric coefficients is used to calculate the solubility product.

Step 2: Calculate the value of [Hg22+].

Assume that ${Hg}_{2} {Cl}_{2}$ each contribute a negligible amount of C $l^{-}$ to 0.010MKCl. This is due to the low solubility of ${Hg}_{2} {Cl}_{2}$ .

From the table 8-1 and given information the required values are,

$μ = 0.010 M [C l^{-}] = 0.010 M γ_{H g^{2 +}} = 0.660 a n d γ_{C r} = 0.899$

Calculate the value of $[{Hg}_{2}^{2 +}]$ using the equation for the solubility product

$K_{sp} = 1.2 \times 10^{- 18} = [{Hg}_{2}^{2 +}] γ_{\lg^{2 +}} {[{Cl}^{-}]}^{2} γ^{2} {Cr}^{2} = [{Hg}_{2}^{2 +}] (0.660) {(0.01)}^{2} {(0.899)}^{2} [{Hg}_{2}^{2 +}] = 2.2 \times 10^{- 14} M$

The value of $[{Hg}_{2}^{2 +}]$ in equilibrium with 0.010M KCI saturated ${Hg}_{2} {Cl}_{2}$ is role="math" localid="1663411773731" $2.2 \times 10^{- 14} M$
