Question

A current of `2` ampere passing for `5` hr through a molten tin salt deposits `22.2 g` of t tin. Find the oxidation number of tin in the salt.

Answer 1

Correct Answer - 2
`Sn^(n+) + n e rarr Sn`
For Sn `" "(w)/(E) = (i xx t)/(96500)`
`(22.2)/(118//n) = (2 xx 5 xx 60 xx 60)/(96500) " " :. n = 2`
