When 25 g of `Na_(2)SO_(4)` is dissolved in `10^(3)` Kg of solution, its concentration will be

12.5 g of H_(2)SO_(4) are dissolved in water to make 1250 ml of solution. The concentration in normality is :

Define a solution. If 10 mL of H_(2)SO_(4) are dissolved in 90 mL of water, calculate concentration of solution.

If 1.34g Na_(2)C_(2)O_(4) is dissolved in 500 mL of water and this solution is titrated with M/10 KMnO_(4) solution in acidic medium, the volume of KMnO_(4) used is :

If 1.34g Na_(2)C_(2)O_(4) is dissolved in 500 mL of water and this solution is titrated with M/10 KMnO_(4) solution in acidic medium, the volume of KMnO_(4) used is :

Calculate the boiling point of solution when 2 g of Na_2SO_4 (M=142gmol^-1) was dissolved in 50 g of water, assuming Na_2SO_4 undergoes complete ionization. (K_b for water=0.52 K kg mol^-1) .

When SO_(2) is passed into an Na_(2)CO_(3) solution, it produces
