How may gram of 83.4% pure sodium sulphate can be produced form 250 g of 95% pure NaCl.

A

`288.2g`

B

`237.5g`

C

`345.4g`

D

`187.2g`

Text Solution

Verified by Experts

The correct Answer is:
C
`2NaCl+H_(4)SO_(4)rarrNa_(2)SO_(4)+2HCl`
Amount of pure `NaCl=250xx(95)/(100)=237.5g`
`2xx58.5gNaCl-142gNa_(2)SO_(4)`
`237.5gNaCl-288.2gNa_(2)SO_(4)`
To get 83.4 pure `Na_(2)SO_(4)` - take 100g impure sample of `Na_(2)SO_(4)`
To get 288.2g pure `Na_(2)SO_(4)` - take 345.4g impure `Na_(2)SO_(4)`
