Questions and Answers

Which one of these is the correct equation to calculate the weight of copper deposited at the cathode?

Weight of copper = Current (A) × Time (s) × ECE of copper

Weight of copper = Current (A) × Time (h) × ECE of copper (correct)

Weight of copper = Current (A) ÷ Time (s) × ECE of copper

Weight of copper = Current (A) × Time (min) × ECE of copper

Which one of these is the correct equation to calculate the ECE of silver?

ECE of silver = Weight of silver deposited × Current (A) ÷ Time (s)

ECE of silver = Weight of silver deposited × Current (A) ÷ Time (min)

ECE of silver = Weight of silver deposited ÷ Current (A) × Time (min)

ECE of silver = Weight of silver deposited ÷ Current (A) × Time (s) (correct)

Which one of these is the correct equation to calculate the equivalent weight of the metal?

Equivalent weight of the metal = Current (A) × Time (min) ÷ Weight of metal deposited

Equivalent weight of the metal = Current (A) × Time (h) ÷ Weight of metal deposited

Equivalent weight of the metal = Current (A) ÷ Time (s) × Weight of metal deposited

Equivalent weight of the metal = Current (A) × Time (s) ÷ Weight of metal deposited (correct)
