Reactivity Series
Class 10 Science: metals and non-metals (reactivity series, displacement)
Dip iron, copper, zinc and more into salt solutions. See which metal pushes another out, then rank the metals by reactivity.
Words to know
- Reactivity series
- A list of metals in order of how readily they react.
- Displacement
- A reaction in which a more reactive metal pushes a less reactive metal out of its compound.
- Salt solution
- A solution of a metal compound in water, such as copper sulphate.
- Copper sulphate
- A blue salt. Its colour fades when a more reactive metal displaces the copper.
- Iron sulphate
- A pale green salt formed when iron displaces copper from copper sulphate.
