Q. 55.0( 3 Votes )

You have just won a medal made of 22-carat gold. Have you just procured a pure substance or impure substance?

Answer :

It is an impure substance since the purity of gold is measured in terms of carat. 24 carat is the pure form of gold so 22 carat gold = (22/24) ×100 = is 91.66 % pure only. It is actually alloy of gold, silver and nickel.
