25mL of `2N HCl, 50 mL "of" 4N HNO_(3) and xmL H_(2)SO_(4)` are mixed together and the total volume is made up to 1L after dilution. 50mL if this acid ixture completely reacteed with 25mL of a `1 N Na_(2)CO_(3)` solution. The value of x is:

A

250 mL

B

62.5 mL

C

100 mL

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
m-eq of acid's in 50 mL =m-eq. of `Na_2CO_3 implies 25xx2+50xx4+2xx2x =100/50xx25xx1`
x=62.5 mL
