Question

What volume of 0.10 M H2SO4  must be added to 50 ml of a 0.10 M NaOH solution to make a solution in which the molarity of the H2SO4 is 0.050 M?

C

100 ml

D

150 ml

Solution

The correct option is A

50 ml


2NaOH +H2SO4  Na2SO4 + 2H2O

0.0025 moles  of H2SO4  will neutralise 0.005 moles  NaOH

So for 0.01 V moles H2SO4 there will be 0.01v-0.0025 moles H2SO4 left unused in the total volume (v+50ml) of solution . 

The concentration here will be

0.010.0025v+50×1000 = 0.05M

100V2.5V+50 =0.05

100V2.5V+50= 2.5+2.5

99.95V= 5

V= 0.05002L

V= 50.02ML
