A solution of a salt of a metal was electrolysed for ` 150 ` minutes with a current of ` 0 . 15` amperes. The weight of metal deposited was `0. 783 g`. The equivalent weight to the metal is .

A

55.97 gm

B

65.97 gm

C

75.97gm

D

85.97 gm

Text Solution

Verified by Experts

The correct Answer is:
A
Time(t)=150min=9000sec
Current(I)=0.15A
Weight of metal (w)=0.783g.
We know `Q=Ixxt=0.15xx9000=1350C.` Since 1350 C
of electricity will deposited`(0.783xx96500)/(1350)=55.97g`.
