22.7 mL of (N/10) `Na_(2)CO_(3)` solution neutralises 10.2 mL of a dilute `H_(2)SO_(4)` solution. The volume of water that must be added to 400 mL of this `H_(2)SO_(4)` solution in order to make it exactly N/10.

1.325 g of anhydrous sodium carbonate is dissolved in water and the solution is made up to 250 mL. On titration 25 mL of this solution neutralises 20 mL of a solution of H_2SO_4 . HOW much water should be added to 450 mL of this acid solution to make it exactly N/12 ?

Find the volume (in mL) of 0.2 (N) NaOH solution required to neutralise 25 mL of 0.2(N) H_(2)SO_(4) solution.

30 ml of N/10 HC1 is required to neutralize 50 ml of a sodium carbonate solution. What volume of water (in ml) must be added to 30 ml of Na_2 CO_3 solution so that the final solution has concentration N/50?
