Question

what is the importance of metal reactivity series​

Answer 1

Answer:

The reactivity series allows us to predict correctly how metals will react. Another importance is that so we can use displacement. We can spot a more reactive metal allowing us to displace a less reactive metal from a compound or an equation.

Answer 2

Importance of Metal Reactivity Series are:

• Metal Reactivity Series are used in Displacement reaction.
• It is used in the reaction between water and metals.
• In the reaction between metals and acids.

What are metal reactivity series?

Metal reactivity series is a chart of listing the metals in the order of decreasing reactivity.

• As in Displacement reaction less reactive metal is displaced by more reactive metal. By metal reactivity series we came to know which metal is displaced by another metal.
• When the metals from Potassium and Calcium react with cold water             it will release Hydrogen gas.

See the below reaction:

K(s)        +            $H_2O$   →           KOH(aq)              +                  1/2 $H_2$ (g)

Potassium      water              Potassium Hydroxide                Hydrogen

• Metals like Lead and others which are more reactive than Lead can react with HCl and $H_2SO_4$ to form salts. We can predict the reaction by reactivity series.

Lets see the reaction between Lead with Hydrochloric acid and Sulphuric acid.

Pb (s)      + 2HCl (aq)           →              $PbCl_2$ (aq)           +       $H_2$ (g)

Lead        Hydrochloric acid          Lead chloride                  Hydrogen

Pb (s)      +   $2H_2SO_4$             →     $PbSO_4$              +   $SO_2$                   +   $H_2O$

Lead         Sulphuric acid            Lead Sulphate      Sulphur dioxide    water
