Best Answer

The carbonate ion is the conjugate base of a diprotic acid. If you react an equal number of moles of hydrochloric acid and sodium carbonate, the carbonate will only be partially neutralized you will get a mixture of sodium chloride and sodium bicarbonate.

HCl + Na2CO3 --> NaHCO3 + NaCl

Only by adding twice as many moles of HCl will you completely neutralize the sodium carbonate.

2HCl + Na2CO3 --> 2NaCl + H2O + CO2
