Question

6. 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

Answer:

A glitter appears after some time because copper coin displaces silver from silver nitrate and forms copper nitrate.

AgNO3 + Cu = Cu(NO3)2

(Silver nitrate) (copper coin) (copper nitrate)

Answer 2

Answer:

Copper is more reactive than silver. Hence, displacement reaction occurs. When copper coin is dipped in silver nitrate solution, it forms copper nitrate and silver metal. A shining white deposit of silver metal is formed on copper coin. The grey solid crystal (glitters) of Ag metal appears on the copper coin and solution turns blue in colour.

Balanced equation :

2AgNO3 (aq) + Cu (s) ➝ Cu(NO3) 2 (aq) + 2Ag (s)
