Question

Mohan,a student of chemistry was performing some chemical reactions.hetook some copper coins and dipped in silver nitrate solution for three days he observed that the colour of the solution has changed and coins are giving white shiny appearance​

Answer 1

Answer:

as in reactivity series of metal, copper placed above silver.which means copper is more ractive in silver. when a student kept this copper metal is silver nitrate solution that a silver shiny appearance deposite on copper.

Explanation:

the explantaion of this answer is, being more reactive in nature, copper displace silver from silver nitrate solution and and a formation of copper nitrtae is occor which is shiny in apperence on the copper metal.

Answer 2

Answer:

A displacement reaction has taken place here. Here copper is more reactive than silver. More reactive element always have the tendency to become ions. so copper now loses electrons and becomes an ion and silver ions in the solution gains this electron and gets deposited in the coin
