Chemistry
Bicarbonate is an ion with the chemical formula HCO3–. In the presence of water, it results in the following reactions:
(i) HCO3–(aq) + H2O(l) → H2CO3(aq) + OH–(aq)
(ii) HCO3–(aq) + H2O(l) → CO32–(aq) + H3O+(aq)
In the above reactions, the bicarbonate ion acts as _____.
a) a strong acid
b) a strong base
