One g of a mixture of Na2CO3 and NaHCO3 consumes y equivalent of HCl for complete neutralization. One g of the mixture is strongly heated, then cooled and the residue treated with HCl. How many equivalent of HCl would be required for complete neutralization?
y equivalent
The no. of equivalent of NaHCO3 = No. Of equivalent of Na2CO3 formed. Thus, same equivalent of HCl will be used.
