Question

what is reactivity series of metal

Answer 1

heya!! friend!!

reactivity series of metal are a list of metals in which metals are arranged in their decreasing order of reactivity(activity) is called activity series :)

HOPE IT HELPS YA :-)

Answer 2

It is an arrangement of metals in decreasing order of their reactivities.

Example:
Potassium at the top of the series is the most reactive among all the metals of the series.Zinc displaces copper from copper sulphate solution to form zinc sulphate and metallic copper. But, Copper do not displaces zinc from zinc sulphate .This is because Zinc is placed above the Copper in the Reactivity Series of metals.Zn + CuSO4 → ZnSO4 + Cu
Cu + ZnSO4 → No Reaction
Zinc reacts with dilute hydrochloric acid to produce hydrogen gas, whereas Copper does not react with dilute hydrochloric acid. This is because zinc is placed above the hydrogen while copper is placed below hydrogen in the reactivity series of metals.Zn + 2HCl → ZnCl2 + H2
Cu+ 2HCl → No Reaction
