50 ml of 0.2 M HCl is added to 30 ml of 0.1 MKOH solution. Find the pH of the solution.

Given two mixtures: (I) NaOH and Na_(2)CO_(3) and (II) NaHCO_(3) and Na_(2)CO_(3) . 100 ml of mixture I required w and x ml of 1 M HCl is separate titrations using phenophthalein and methyl orange indicators while 100 ml of mixture II required y and z ml of same HCl solutioni in separate titrations using the same indicators.

In the mixture of NaHCO_(3) and NaCO_(3) , volume of a given HCl required is x ml with phenolphathalein indicator and further y mL is required with methyl orange indicator. Hence volume of HCl for complete reaction of NaHCO_(3) present in the original mixture is

Solution ''X'' contains Na_(2)CO_(3) and NaHCO_(3), 20 ml of X when titrated using methyl organge indicator consumed 60 ml of 0.1M HCI solution. In another experiment, 20 ml of X solution when titrated using phenolphthalein consumed 20 ml of 0.1 M HCl solution. The concentraions ("in mol lit"^(-1)) of Na_(2)CO_(3) and NaHCO_(3) in X are respectively)
