Question

Why chromium is used for electroplating

Answer 1

Answer:

Explanation:

1. Chromium has a shiny appearance.

2. It does not corrode.

3. It resists scratches.

4. However it is expensive so it is not economical to maje the whole object out of chromium so a plating of chromium is done on less expensive metal.

chromium is an expensive,hard and shiny metal. only a thin layer of chromium is electroplated over the other metal like iron to make handle bars of bicycle,wheel rim, etc,. they are used as they resist scratches and prevent corrosion when electroplated by chromium. it is very useful but very expensive

Answer 2

Answer:

Chromium has a shiny appearance, does not corrode and resists scratches. However chromium is expensive and it may not be to make the whole object out of chromium. So the object is made from a cheaper metal and only a coating of chromium over it is done.

The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness.
