A mixture of one mole of sodium hydrogen carbonate is titrated against a tribasic acid H3X.What is the number of moles of the acid required for complete reaction?
The ans is 1
but I calculate 0.33333
H3X + 3NaHCO3 -->3CO2+3H2O+Na3X

No. of moles: 1 mol. y
y = 1/3 = 0.333333333333333333333333333333333mol.
Therefore, the answer is wrong, your calculation is correct.
