0.066 ~g of metal was deposited when a current of 2 ampere is passed through a metal ion solution for 100 seconds. What is the electrochemical equivalent (in gram coulomb ⁻¹ ) of the metal?
Options
- A3.3 10⁻⁶
- B3.3 10⁻⁴
- C0.033
- D3.3
Correct answer
B. 3.3 10⁻⁴
Step-by-step solution
w=z i tz= w i t = 0.66 2 100 =3.3 10⁻⁴ ~g / coulomb
