What is Reactivity series of metals. Arrange iron,gold,copper and magnesium in decreasing order of reactivity and give reasons .
Dear Student,
A more reactive metal can be defined as the one which can displace other metal from its aqueous solution when put together. This reaction is called displacement reaction. In short we can say that more reactive metal will form compounds and does not remains in 0 Oxidation state if a less reactive metal is forming compound.
For eg-
here A metal is displacing B metal from its aqueous salt BC and itself forming compound with C. The reactivity of metal is defined by this displacement and a series is developed by scientist experimentally which provide information for the reactivity order.
Answer- Here order will be Magnesium > iron > copper > gold
Regards
