<u>Answer:</u> The chemical equations and equilibrium constant expression for each ionization steps is written below.
<u>Explanation:</u>
The chemical formula of carbonic acid is . It is a diprotic weak acid which means that it will release two hydrogen ions when dissolved in water
The chemical equation for the first dissociation of carbonic acid follows:
The expression of first equilibrium constant equation follows:
The chemical equation for the second dissociation of carbonic acid follows:
The expression of second equilibrium constant equation follows:
Hence, the chemical equations and equilibrium constant expression for each ionization steps is written above.
