Current Electricity

  1. A steady current of 1.5 amp flows through a copper voltameter for 10 minutes. If the electrochemical equivalent of copper is 30 × 10–5 g coulomb–1, the mass of copper deposited on the electrode will be​
    1. 0.50 g
    2. 0.67 g ​
    3. 0.27 g ​
    4. 0.40 g.
Correct Option: C

We have,  m = ZIt
​where, Z is the electrochemical equivalent of copper. ​
⇒ m = 30 x 10-5 x 1.5 x 10 x 60
​= 0.27 gm.
