Carbonic acid, H2CO3(aq), is a chemical substance which plays an important role in

controlling the pH of body fluids. In aqueous solution it produces HCO3-(aq) and CO32-(aq) as shown below:

H2CO3(aq) + H2O() ® H3O+(aq) + HCO3-(aq)

HCO3-(aq) + H2O() ® H3O+(aq) + CO32-(aq)

In the above equilibrium reactions, H2CO3(aq) is a(n)
