Question

what are the essential conditions that help in getting a smooth and firm deposit during electroplating?​

Answer 1

plzzzzz mark me brainliast and follow me

List the condition that help in getting a smooth and firm...

Small current is passed for longer time.

Proper choice of electrode and electrolyte. e.g. For copper-plating, copper sulphate soln is used as electrolyte.

Surface to be plated must be cleaned (polishing) before electroplating.

Answer 2

Answer:

The condition that help in getting a smooth and firm deposition during electroplating:-

1. Small current is passed for longer time.
2. Proper choice of electrode and electrolyte. e.g. For copper-plating, copper sulphate soln is used as electrolyte.
3. Surface to be plated must be cleaned (polishing) before electroplating.

Improving the Electroplating Process using pH Control

1. Increasing the concentration of metal ions in electroplating solution.
2. Increasing agitation of the solution near the cathode.
3. Increasing operating temperature.
