The atomic weight of silver and copper are 108 and 64. A silver voltameter and a copper voltameter are connected in series and when current is passed `10.8` gm of silver is deposited. The mass of copper deposited will be

A

6.4 g

B

3.2g

C

3.2g

D

10.8 g

Text Solution

Verified by Experts

The correct Answer is:
C
According to faraday.s second law of electrolysis,
`m_1/m_2 = (E )/(E_2)`
`m_(cu) = (10.8 xx 32)/(108 xx 10) = 32 g `
