One day Reeta went to a jeweller's shop with her mother. Her mother gave an old gold jewellery to the Goldsmith to polish. Next day when they bought the jewellery back,they found that there was a slight loss in its weight. Can you suggest a reason for the loss in weight?
Answers
Answer:
It's because of aqua regia.
Explanation:
In order to polish a gold ornament,the jewellers dip the ornament in a liquid called aqua regia, which is a mixture of hydrochloric acid and nitric acid. On getting the environment of aqua regia, the gold ornament shreds off the old dull layer and reveals the inner shining layer. This causes the loss in weight of the jewellery.(Please mark me as the Brainliest.
