Metals reaction with water.
When metals react with water they form positive ions, they can be ordered by how fast, vigorous the reaction is in the reactivity series.
A more reactive metal will displace a less reactive metal from a non-metal, this is known as displacement.
eg
placing a magnesium ribbon in copper sulfate, the magnesium will react with the sulfate to form magnesium sulfate plus copper.
Work out an order of reactivity based on reactions
Metal Copper nitrate Magnesium nitrate silver nitrate zinc nitrate
Cu No reaction no reaction silver crystals no reaction Mg Brown solid no reaction silver solid silver solid Ag no reaction no reaction no reaction no reaction Zn brown solid no reaction silver solid no reaction
Reactivity order
Mg, Zn, Cu, Ag
