Question

When a copper coin is dipped in silver nitrate solution, a glitter appears on the coin after some time. Why does this happen? Write the chemical equation.

Answer 1

Hey!

Here is your answer!
_______________________________

When a copper coin is dipped in silver nitrate solution, a glitter appears on the coin after some time. This is because, copper being more reactive than silver displaces silver from its salt solution to form copper nitrate and the silver from the solution gets deposited on the coin giving a glittery appearance to the coin.

The chemical equation involved is :

Cu + 2AgNO3 => Cu(NO3)2 + 2Ag

Hope it's satisfactory!

Answer 2

Dear Student,

◆ Answer with Explaination -

• As copper is more reactive than silver, it will replace silver from silver nitrate solution and form copper nitrate.

2AgNO3 + Cu --> Cu(NO3)2 + 2Ag

• Glitter appears on the coin due to deposition of copper nitrate.

◆ Displacement reaction -

• Reaction in which one element displaces another element from its compound is called displacement reaction.
• Usually a highly reactive element displaces a less reactive element in the reaction.

Thanks dear..
