what is reactivity series? how does the reactivity series of metals help in predicting the relative activities of various metals?
Answers
Answer:
The reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending order of their reactivities. The data provided by the reactivity series can be used to predict whether a metal can displace another in a single displacement reaction. It can also be used to obtain information on the reactivity of metals towards water and acids.
Explanation:
The reactivity series of metals (or the activity series) is a series obtained on arranging the metals in the descending order of their reactivities.
- The most reactive metal is placed at the top and the rest are put in descending order so that the least reactive is at the bottom.
- The above placed metal can displace below placed metal from its salt solution due to its high reactivity.
- A major portion of reactivity series is given below:
Caesium > Francium > Rubidium > Potassium > Sodium > Lithium > Calcium > Magnesium > Aluminium > Manganese > Zinc > Iron > Cobalt > Nickel > Tin > Lead > Copper > Mercury > Silver > Gold > Platinum.
