What volume of 0.05(N) H(2)SO(4) will be...

What volume of 0.05(N) `H_(2)SO_(4)` will be required to neutralise that alkali formed by passing a current of 0.4 A for 5 min through a dilute solution of `NaCl`?

Text Solution

Verified by Experts

Quantity of electricity `=0.4xx(5xx60)=120C`.
96500C of electricity produce 1 g-eq of NaOH.
So, 120 C of electricity will produce `(120)/(96500)="0.00124 grams - equivalent of NaOH."`
Let, the volume of `H_(2)SO_(4)` required = x mL.
`"1000 mL of 1 (N) "H_(2)SO_(4)" solution "-="1 g -eq of NaOH"`
`"x mL of 0.05 (N) "H_(2)SO_(4)-=(x xx 0.05)/(1000)" g-eq of NaOH"`
So, `x xx(0.05)/(1000)=0.00124" or, x"=(0.00124xx1000)/(0.05)="24.80 mL."`
