A certain metal salt solution is electrolysed in series with a silver coulometer. The weight of silver and the metal deposited are `0.5094g` and `0.2653g`. Calculate the valency of the metal if its atomic weight is nearly that of silver.

Text Solution

Verified by Experts

The correct Answer is:
2
`(W_(Ag))/(W_("metal"))=(E_(Ag))/(E_(M))=(108)/((108)/(n))=n`
`n=(0.5094)/(0.2653)=1.92`
`n=2`.
