In aqueous solution the ionization constants for carbonic acid areK1 =...

As H₂CO₃ is a weak acid so the concentration of H₂CO₃ will remain 0.034 as 0.034 >> x.

is again a weak acid (weaker than H₂CO₃) with x >> y.

Note : [H₃O⁺] = H⁺ from first step (x) and from second step (y) = (x + y)

So the concentration of

concentrations obtained from the first step. As the dissociation will be very low in second step so there will be no change in these concentrations.
Thus the final concentrations are
