Question

The molar solubility of AgBr in pure water is 7.3x10^-7 M. Calculate the Ksp.

Answer #1

Determine the K_{sp} of silver bromide, given that its
molar solubility is 7.3 x 10¯^{7} moles per liter.

When AgBr dissolves, it dissociates like this:

AgBr (s) ⇌ Ag^{+} (aq) + Br¯ (aq)

The K_{sp} expression is:

K_{sp} = [Ag^{+}] [Br¯]

There is a 1:1 molar ratio between the AgBr that dissolves and
Ag^{+} that is in solution. In like manner, there is a 1:1
molar ratio between dissolved AgBr and Br¯ in solution. This means
that, when 7.3 x 10¯^{7}mole per liter of AgBr dissolves,
it produces 7.3 x 10¯^{7} mole per liter of Ag^{+}
and 7.3 x 10¯^{7} mole per liter of Br¯ in solution.

Putting the values into the K_{sp} expression, we
obtain:

**K _{sp} = (7.3 x 10¯^{7}) (7.3 x
10¯^{7}) = 5.329 x 10¯^{13}**
