Question

when copper turnings are added to colourless silver nitrate solution a blue coloured solution is formed after sometime explain how this is possible along with reaction

Answer 1

cu+ AgNo3-cuNo3+AG...

Answer 2

Copper is more reactive than silver so it will displace silver nitrate solution .The reaction is as follows : cu+2Ag(NO3)2-----> Cu(NO3)2+2Ag.
The colourless solution of silver nitrate will turn to blue due to formation of copper nitrate and silver metal will deposit on the copper turnings.
