A mixutre solution of KOH and `Na_2CO_3` requires 15 " mL of " `(N)/(20)` HCl when titrated with phenolphthalein as indicator.But the same amoound of the solutions when titrated with methyl orange as indicator requires 25 " mL of " the same acid. Calculate the amount of KOH and `Na_2CO_3` present in the solution.

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.
