`10mL ` of an `N-HCI, 20mL` of `N/2 H_2 SO_4 and 30 mL` of `N/3 HNO_3` are mixed together and volume made to one litre. The normality of `H^+` in the resulting solution is :

25mL of 2N HCI, 50 mL of 4N HNO_3 and x mL of 2MH_2 SO_4 are mixed together and the total volume is made up to 1L after dilution. 50mL of this acid mixture completely reacted with 25mL of a 1NNa_2 CO_3 solution. The value of x is :

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:

If 100 ml of 1N H2SO4 is mixed with 200 ml of 1N HCl solution . calculate the normality of resulting solution .

2.5 litre of 1 M NaOH solution are mixed and another 3 litre of 0.5 M NaOH solution. Then the molarity of the resulting solution is

50mL of 20.8% (w/V) Ba CI_2 (aq) and 100mL of 9.8% mL(w/V) H_2SO_4 (aq) solutions are mixed. Molarity of Cl^(-) ion in the resulting solution is : (At mass of Ba=137 )

To a 10mL of 10^(-3) N H_(2)SO_(4) solution water has been to make the total volume of one litre. Its pOH would be :

100 ml decinormal HCl is mixed to 100ml seminormal H2SO4 solution . calculate the normality of resulting mixture.

200 ml of N/10 H2SO4 is mixed into 300ml N/100 NaOH . calculate normality of resulting mixture.

If 20 mL of 0.1 M NaOH is added to 30 mL of 0.2 M CH_(3)COOH (pK_(a)=4.74), the pH of the resulting solution is :
