What amount of Cl ₂ gas liberated at anode, if 1 ampere current is passed for 30 minute from NaCl solution?
Options
- A0.66 mol
- B0.33 mol
- C0.66 g
- D0.33 g
Correct answer
C. 0.66 g
Step-by-step solution
2 Cl ⁻ 1 mole Cl ₂ + 2 96500 coulomb 2 e⁻ (At anode) aligned Q & =i t=1 30 60 & =1800 coulomb aligned The amount of chlorine liberated by passing 1800 coulomb of electric charge = 1 1800 71 2 96500 =0.66 ~g
