Question

Question 17 During electrolysis if current is passed for more time then E.C.E value remains ?​

Answer 1

Answer:

When an electric current is passed through an electrolyte, a Chemical reaction takes place. When an electric current is passed through an electrolyte, it is called the electrolysis of water. It is a decomposition reaction. The electrons can move freely in an electrolyte due to electric current.

Explanation:

Hope this will help you.

Answer 2

True, during electrolysis, if the current is passed for more time then the E.C.E value remains the same.

• When electricity is passed through a solution of salt then electrolysis takes place due to the flow of charge and electricity.
• Due to electrolysis mass is deposited at the electrodes.
• The amount of mass deposition is directly proportional to the charge or current.
• So, w = zIt = zQ
• Here, w is mass deposited, I is current, Q is the current, and z is the electrochemical equivalent.
• Electrochemical equivalents depend on the type of material and are calculated by taking the ratio of molecular mass by valency.
• The ECE value of silver is greater than gold and copper.
• ECE value of silver is 10 times the ECE value of copper.
