HCN and HCO3H2O (carbonic acid) are weak acids with relatively low dissociation constants, indicating they do not fully dissociate in solution. Therefore, the major species in solution would be the undissociated forms of these acids (HCN and HCO3H2O) along with water (H2O), which is a product of the carbonic acid formation.
