Q37 of 152 Page 46

Express the following facts in the form of a balanced chemical equation:

"When a strip of copper metal is placed in a solution of silver nitrate, metallic silver is precipitated and a solution containing copper nitrate is formed".

Cu (s) + 2AgN03 (aq.) Cu(N03)2 (aq.) +2Ag (s)

Copper displaces Silver to form copper Nitrate solution and Silver metal is formed as precipitate.
