What are the strong bases?

Bases - Those substances when present in their aqueous form, releases ${\mathrm{OH}}^{-}$ions or Hydroxide ions are called bases.

1. They are bitter in taste.
2. Readily loses Hydroxide ions.

Alkali - Those bases which are soluble in water are called alkali.

For example, Potassium Hydroxide ($\mathrm{KOH}$), Sodium Hydroxide ($\mathrm{NaOH}$)

On the bases of release of ions they are classified into Weak Bases and Strong Bases.

Strong Bases - The ability of the compounds to remove a proton from a very weak acid or completely dissociate into its ions when present in water are known as Strong bases.

1. They possesses pH range from 7 to 14.
2. They shows blue to dark green colour on universal indicator.
3. They release large amount of Hydroxide ions.
4. They conduct electricity.
