Displacement reactions MCQ - Practice Questions with Answers

In a displacement reaction, a more reactive metal displaces a less reactive metal from its salt solution. Copper is more reactive than silver, so copper placed in AgNO3 solution displaces silver and forms copper nitrate. Copper cannot displace iron from FeSO4 because iron is above copper in the reactivity series. Silver cannot displace copper from CuSO4 because silver is less reactive than copper. Copper also cannot displace sodium from NaCl, as sodium is far more reactive than copper.
