A mixed solution of potassium hydroxide and sodium carbonate required 15 mL of an N/20 HCl solution when titrated with phenolphthalein as an indicator. But the same amount of the solution, when titrated with methyl orange as an indicator , required 25 mL of the same acid. The amount of KOH present in the solution is :

NaOH and Na_(2)CO_(3) are dissolvedin 200 ml aqueous solution. In the presence of phenolphthalein indicator. 17.5 ml of 0.1N HCl are used to titrate this solution. Now methyl orange is added in the same solution titrated and it requires 2.5ml of the same HCl . Calculate the normality of NaOH and Na_(2)CO_(3) and their mass present in the solution.

30 " mL of " a solution of mixture of Na_2CO_3 and NaHCO_3 required 12 " mL of " 0.05 M H_2SO_4 using phenolphthalein as indicator. With methyl orange 30 " mL of " the same solution required 40 " mL of " same H_2SO_4 . Calculate the amount of Na_2CO_3 and NaHCO_3 per litre in the mnixture.

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:
