A colourless salt X has 50% `Na_(2)SO_(3)` and 50% `H_(2)O` . How much of `SO_(2)` at NTP is obtained when 2.52 g of X reacts with excess of dil . `H_(2)SO_(4)` ?

Text Solution

Verified by Experts

(X):`Na_(2)SO_(3).7H_(2)O`
`Na_(2)SO_(3).7H_(2)O+H_(2)SO_(4)toNa_(2)SO_(4)+SO_(2)uparrow+8H_(2)O`
`SO_(2)`:0.224L at NTP from 2.52 g `Na_(2)SO_(3).7H_(2)O`
