3 ampere current was passed through an aqueous solution of an unknown salt of Pd for 1 hr 2.977 g of `Pd^(n+)` was deposited at cathode. Find the value of n. (atomic weight of Pd is 106.4)

Text Solution

Verified by Experts

The correct Answer is:
4
`3 xx 60 xx 60 c to 2.977 gm , n xx 96500 to 106.4 `
` n xx 96500 to (3 xx 60 xx 106.4 xx 60)/(2.977) implies n =4 `
