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

✔ 最佳答案
3NaHCO3 + H3X ---> 3CO2 + 3H2O + Na3XNo. of moles: 1 mol. y
y = 1/3 = 0.333333333333333333333333333333333mol.
Therefore, the answer is wrong, your calculation is correct.
