What would happen if a copper coin were kept immersed in a solution of silver nitrate write the word equation also?
copper is placed above the silver in the ractivity series which indicates that copper is more reactive than silver . when a copper coin is kept immersed in a solution of siler nitrate ,silver from its solution will deposit on copper coin . copper slowly displaces silver from the silver nitrate solution and the colour of solution changes from colourless to blue due to the formation of copper nitrate . the copper coin will disappear and silver will percipate out .
