Question

What happens when a base reacts with a metal?


Solution

Characteristics of a base:

  • Bases are bitter in taste and have a slippery texture.
  • When a base reacts with an acid, a salt is formed.
  • A base turns the color of a red litmus paper into blue color.

Reaction of a base with a metal:

  • When a base reacts with a metal, it involves the formation of salt along with the liberation of hydrogen gas.
  • The word equation can be written as follows:

Metal+BaseSalt+Hydrogen

Example:

  • When sodium hydroxide NaOH reacts with zinc metal Zn, sodium zincate is formed along with the liberation of hydrogen gas H2.

Zn(s)+2NaOH(aq)Na2ZnO2(aq)+H2(g)
