Dividing the mass by the volume.
Answer : The ions present in the solution of
are
and
in aqueous state.
Explanation :
When
is in aqueous solution then they dissociates into their ions.
The reaction in aqueous medium is,

The charge on potassium ion is +1 and on carbonate ion is -2. To neutralize the charge on carbonate ion, two potassium ion must be used.
Therefore, the ions present in solution of
are
and [tex]CO^{2-}_3[tex] in aqueous state.
