`4.0` g of NaOH and `4.9` g of `H_(2)SO_(4)` are dissolved in water and volume is made upto 250 mL.
The pH of this solution is:

12 g of H_(2)SO_(4) are dissolved in water to make 1200 ml of solution. The normality of the solution is

10.875 g of a mixture of NaCl and Na_(2)CO_(3) was dissolved in water and the volume made up to 250 mL, 20 mL of this solution required 75.5 mL of (N)/(10) H_(2)SO_(4) . Find out the percentage composition of the mixture.

8g NaOH is dissolved in water and the solution is made upto 500 mL. find the molarity of solution.

10.875 g of a mixture of NaCI and Na_2CO_3 was dissolved in water and the volume was made up to 250 mL. 20.0 mL of this solution required 75.5 mL of N/10 H_2SO_4 . Find out the percentage composition of the mixture.

2g of NaOH and 4.9 g of H_2SO_4 ​were mixed and volume is made 1 litre. The normality of the resulting solution will be:
