Explanation:
will dissociate into ions as follows.
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.
=
+ x
=
+ 2x
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,
x = M
Thus, we can conclude that molar solubility of is
M.
