Question

Consider the Following Statement. 

A. Electroplating is done for making metals resistive against Corrosion

B. Electroplating is done for shiny appearance. 

C. Electroplating can reduce cost by reducing the use of costly metals.

Which of the following statement is correct. 

1. A,B
2.

A,C

3. B,C
4. A,B, and C

Answer 1

Correct Answer - Option 4 : A,B, and C

Concept:

Electroplating: 

• It is the process of depositing a layer of any desired metal on another material by using electricity. 
• The process has a wide range of industrial applications. 
• It forms a protective layer over metal and makes it corrosion resistant. 
• It also gives a shiny appearance to metals.

How Electroplating reduces cost?

• Chromium metal is corrosion resistant and has a shiny appearance. 
• But the metal is very costly and it is not corrosion-resistant. 
• So, applying electroplating of Chromium over cheap metal provides a cheap alternative of chromium. 

Explanation:

So, electroplating has benefits such as 

- providing resistance against corrosion

- providing the lustrous appearance

- cost benefit 

So, All statements A,B and C are correct. 

• Electroplating is done by the process of electrolysis. 
• The process is also used for coating silver, gold over cheaper metal to form jewelry.
