Question

Kavitha bought a new silver anklet. After a month, she found that
the anklets had lost their luster and turned black. She had a doubt that
they were not pure silver. But her mother told her that they were of
pure silver. She washed her silver anklets with lemon juice and found
that the silver anklets had got the luster back.

that silver would not corrode and it was even true during that time but now due to very high ammount of sulphur in air silver corrode.

but still it's a Nobel metal and is expensive
