Q.11. What is meant by reactivity series of metals? Arrange the following in an increasing order of their
reactivities towards water.
Zinc, Iron, Magnesium, Sodium.
Answers
Answer:
a vertical arrangements of metals in which the highest reactive metal is placed at the top and the then of less reactive and the least reactive bat the bottom , is called reactivity series of metals.
sodium > magnesium > zinc> iron.

Arrange the above given metals in an increasing order of their reactivity toward water
having trouble with your answer?
here it is....!!
____________________________________________
The reactivities of metals towards oxygen,water and acids can be compared by displacement reactions. A more reactive metal displaces a less reactive metal from its salt solutions. Based on their displacement reactions, the metals have been arranged in a vertical column in the order of decreasing reactivities. This is called the reactivity series.
The decreasing order of reactivity of zinc, iron, magnesium and sodium is :
Sodium > Magnesium > Zinc > Iron
