3.65gm equimole mixture of `NaOH` and `Na_(2)CO_(3)` is titrated against `0.1M HCl` using phenolphathalein as an indicator, `V_(1)mL` of acid was required to reach end point. In another experiment `3.65gm` of same mixture is titrated against 0.2M HCl using methyl orange as an indicator, `V_(2)mL` of acid was required to reach end point. `V_(1)+V_(2)` is :

When Na_(2)CO_(3) solution is titrated against HCl solution, the indicator used is

200 " mL of " a solution of a mixture of NaOH and Na_2CO_3 was first titrated with 0.1 M HCl using phenolphthalein indicator. 17.5 " mL of " HCl was required for the same HCl was again required for next end point. Find the amount of NaOH and Na_2CO_3 in the mixture.

0.4 g mixture of NaOH, Na_2CO_3 , and some inert N impurities was first titrated with N/(10) HCl using phenolphthalein as an indicator, 17.5 ml. of HCI was required at the end point. After this methyl orange was added and titrated. 1.5 mL of same HCl was required for the next end point. The weight percentage of Na_2CO_3 , in the mixture is (Rounded-off to the nearest integer)

A mixture NaOH+Na_(2)CO_(3) required 25mL of 0.1 M HCl using phenolpththalein as the indicator. However, the same amount of the mixture required 30mL of 0.1M HCl when methyl orange was used as the indicator. The molar ration of NaOH and Na_(2)CO_(3) in the mixture was:
