Question

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 brought the jewellery back,
they found that there was a slight
loss in its weight. Can you suggest a
reason for the loss in weight?
​

Answer 1

Answer:

They observed a loss in weight as the goldsmith washed the jewellery with an  acidic solution such as aqua reiga which dissovled some metal in it.

Answer 2

Answer:

The goldsmith washed the jewellery with acidic solution such as aqua regia.

This aqua regia solution dissolves metal in it.

Hence there was a slight loss in its weight.
