1 M NaOH solution was slowly added in to...

1 M NaOH solution was slowly added in to 1000 mL of 183.75 g impure `H_(2)SO_(4)` solution and the following plot was obtained. The percentage purity of `H_(2)SO_(4)` sample and slope of the curve respectively are:

A

`75%`

B

`60%`

C

`80%`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
`1M NaOH` solution was slowly…………..
Moles of NaOH consumed when reacted with `H^(+) = 3xx1`
(because `3L` of NaOH is added with `1M` cons.)
moles of `H_(2)SO_(4)` present in sample `= 1.5`
(because every `H_(2)SO_(4)` has `2H^(+)`)
weight of `H_(2)SO_(4)` in sample `= 1.5xx98 = 147g`
`%` purity `= (147)/(183.75)xx100=80%`
