Explanation:
Concentration of is 0.278 M and it is completely ionized into
and
.
This means that =
= 0.278 M
It is given that concentration of is 0.222 M.
As is a weak acid. Therefore, its dissociation will be as follows.
Initially : 0.222 M 0 0.278 M
Change : - x +x +x
Equilibrium : 0.222 M - x x 0.278 M + x
Therefore, dissociation constant for this reaction will be as follows.
Hence, putting the given values into the above formula as follows.
x = 0.00036
As, is 0.00036 M. Therefore, percentage ionization of
will be calculated as follows.
% ionization of =
=
= 0.16 %
Thus, we can conclude that % ionization of is 0.16%.
