Metals And Non-Metals

Que 1. Mrs. Sharma has gone to the jewellers shop to buy gold jewellery. She asks the jeweller, if the Jewellery is made of pure gold. The jeweller assure her that it is 100% gold and nothing has been mixed in it. Mrs. Sharma is happy and buys the necklace.

Answer the following questions based on the above situation: 

(i) was the jeweller right in saying that the necklace is made of 100% gold? 

(ii) What values are promoted by the jeweller? 

(iii) What precautions should you take, while purchasing gold jewellery? 

(iv) Why does Government insist on purchasing Hallmarked jewellery?

Ans. (i) No, he was wrong. Pure gold is very soft and is, therefore, not suitable for making jewellery. It is alloyed with either silver or copper to make it hard. But, sometimes jewellers mix a large quantity of copper and silver in gold, to earn more profit. 

(ii) Untrustworthiness, cheating, cunning. 

(iii) We should always purchase the gold jewellery from a branded shop with proper receipt and Hallmark certificate. 

(iv) Government insists on purchasing hallmarked jewellery as it contains the gold and its alloyed metal (i.e., copper or silver) in a fixed ratio.
