Ferric sulphate on heating gives

A

`2:3`

B

`1:3`

C

`3:1`

D

`3:2`

Text Solution

Verified by Experts

The correct Answer is:
D
`Fe_(2)(SO_(4))_(3) rarr Fe_(2)O_(3) +3SO_(3)`
`400 --------240`
`1000 ------------(240)(400) xx 1000 = 600`
`80 SO_(3) =32S`
`600 g = ?`
`O:S`
`360: 240 rArr (600 xx 32)/(80) = 240`
`3:2`
`W_(0) = 600 - 240 = 360`
