What is the ratio of weights of Ag and A...

What is the ratio of weights of Ag and Al deposited at the respective cathodes when the same current is passed for same period through aqueous `AgNO_(3)` and `Al_(2)(SO_(4))_(3)` solutions.

Text Solution

Verified by Experts

`("mass of Ag")/("mass of Al")=("Equivalent weight of Ag")/("Equivalent weight of Al")`
`=(108)/(9)=12:1`
