Explanation:
Hence,
for this reaction will be as follows.
We take x as the molar solubility of
when we dissolve x moles of solution per liter.
Hence, ionic molarities in the saturated solution will be as follows.
So, equilibrium solubility expression will be as follows.
Each sodium bromide molecule is giving one bromide ion to the solution. Therefore, one solution contains
= 0.10 and there will be no lead ions. So,
= 0
So,
will approximately equals to
.
Hence,![K_{sp} = x[Br^{-}]^{2}_{o}](/tpl/images/0225/0552/ae97c.png)
x =
M
Thus, we can conclude that molar solubility of
is
M.
