A mixture contains 1.0 mole each of NaOH,`Na_(2)``CO_(3)` and `NaHCO_(3)`. When half of mixture is titrated with HCl ,it required x mole of HCl in presence of phenolphthalein. In another experiment ,half of mixture required y mole of same HCl in presence of methyl orange. Find the value of (x+y).

A mixture contains 1.0 mole each of NaOH, Na2CO3 and NaHCO3. When half of mixture is titrated with HCI.it required x mole of HCI in presence of phenolphthalein. In another experiment, half of mixture required y mole of same HCI in presence of methyl orange. Find the value of(x + y)

During the titration of a mixture of Na_(2)CO_(3) and NaHCO_(3) against HCl

In the study of titration of NaOH and Na_(2)CO_(3) . NaOH and NaHCO_(3) , Na_(2)CO_(3) and NaHCO_(3) , phenophthalein and methyl orange are used as indicators. (a). When phenolphthalein is used as an indicator for the above mixture: (i). It indicates complete neutralisation of NaOH or KOH (ii). It indicates half neutralisation of Na_(2)CO_(3) because NaHCO_(3) is formed at the end point. (b). When methyl orange is used as an indicator for the above mixture (i). It indicates complete neutralisation of NaOH or KOH (ii). It indicates half neutralisation of Na_(2)CO_(3) because NaCl is formed at the end point. Q. 1 L solution of Na_(2)CO_(3) and NaOH was made in H_(2)O . 100 " mL of " this solution required 20 " mL of " 0.4 M HCl in the presence of phenolphthalein however, another 100 mL sample of the same solution required 25 " mL of " the same acid in the presence of methyl orange as indicator. What is the molar ratio of Na_(2)CO_(3) and NaOH in the original mixture.
