Chapter 8: QCE (page 182)

Using activities, find $[{Ag}^{+}]$ in $0.060 MKSCN$ saturated with $AgSCN (s)$

Short Answer

Expert verified

The concentration of ${Ag}^{+}$ ion in 0.060MKSCN is $2.9 \times 10^{- 11} M$

Step by step solution

Define the formula for activity species.

Any species' activity value is calculated by multiplying its concentration by its activity coefficient.

For a species C, the activity is given by

$A_{c} = [C] γ_{c}$

where,

A - Activity

[c] - Concentration

- Activity coefficient.

Calculate the activity species.

Given

$0.060 {MKSCN}^{- 1}$ saturated with ${AgSCN}_{(s)}$

The ionic strength $(μ)$ is $0.060 M$ from KSCN,

The solubility product expression

$μ = 0.060 M K_{SP} = [{Ag}^{+}] γ_{{Ag}^{+}} [{SCN}^{-}] γ_{SCN} = 1.1 \times 10^{- 12} At and γ_{SCN} = 0.80 γ_{A g^{-}} = 0.79$

Substitute the values of concentration and activity coefficients into the solubility product expression

$K_{SP} = [{Ag}^{+}] (0.79) [0.060] (0.80) = 1.1 \times 10^{- 12} [{Ag}^{+}]$

The concentration of ${Ag}^{+}$ ion in $0.060 MKSCN is 2.9 \times 10^{- 11} M$
