Correct Answer - A
Equivalent mass of silver = 108
Equivalent mass of aluminium in `(AlCl_(3))=27/3 =9`
`W_(Ag)/W_(Al)=E_(Ag)/E_(Al)`
`54/W_(Al)=108/9`
`W_(Al)=4.5 g`

In an electroplating experiment, m gm of silver is deposited when 4 ampere of current flows for 2 minute . The amount (in gm ) of silver deposited by

Correct Answer - B `(W_(1))/(W_(2)) = (Q_(1))/(Q_(2))` `(W_(1))/(W_(2)) = (I_(1) xx t_(1))/(I_(2) xx t_(2))` `(m)/(W_(2)) = (4 xx 2 xx 60)/(6 xx 40)` `W_(2) = (m)/(2)g`

Calculate similtaneous solubility of silver thiocyanate and silver bromids in water .Given that `K_(sp)` of silver thiocyanate=`10^(-12)` and `K_(sp)`

Let the simultaneous solubility of `AgSCN` be `x` and that of `AgBr` is `y`.Then: `AgSCNhArr underset(x+y)(Ag^(+))+underset(x)(SCN^(-))"",,,,,,,,,,,""AgBrhArr underset(x+y)(Ag^(+))+underset(y)(Br^(-))` `10^(-12)=xx(x+y)`....(i) `5xx10^(-13)=y(x+y)`....(ii) on solving we get `x=2y` so `y=4.08xx10^(-7)M` and `x=8.16xx10^(-7)M`

A certain metal salt solution is electrolysed in series with a silver coulometer. The weights of silver ad the metal deposited are 0.5094 g and 0.2653

Correct Answer - 2 `(W_(Ag))/(W_("metal"))=(E_(Ag))/(E_(M))=(108)/((108)/(n))=n` `n=(0.5094)/(0.2653)=1.92` `n=2`.
