Question

22-carat Gold contains

• A. 22 parts of Gold + 2 parts of Nickel
• B. 22 parts of Gold + 2 parts of Copper
• C. 22 parts of Gold + 22 parts of Silver
• D. 22 parts of Gold + 2 parts of Chromium

Answer 1

The Correct Option is B

22-carat Gold is an alloy often used in jewelry, composed primarily of gold and other metals to increase strength and durability while maintaining significant gold content. The term "carat" refers to the purity of the gold alloy, with 24-carat being pure gold. Calculating the components of a 22-carat gold alloy, we find:

• The gold content of 22-carat gold is 22 parts out of 24 parts total, meaning it contains 91.67% gold.
• The remaining 2 parts out of 24 are composed of other metals, not including pure gold.

The most common alloy composition for 22-carat gold, used particularly in jewelry, is gold mixed with copper. This mixture enhances the strength and workability of the gold. Therefore, the composition is:

Gold	22 parts
Copper	2 parts

• 22 parts of Gold + 2 parts of Copper

Answer 2

Correct answer: 22 parts of Gold + 2 parts of Copper 

Explanation:
22-carat gold means that out of 24 parts, 22 parts are pure gold and the remaining 2 parts are other metals, usually copper or sometimes silver to add strength and hardness.

Pure gold (24-carat) is too soft for making durable jewellery, so copper is added to improve its hardness while maintaining the golden shine.

So, 22-carat gold contains 22 parts gold and 2 parts copper.
