Question

Give two examples of each of a base and an alkali.

Answer 1

Base:

• Oxides or hydroxides of metals that react with the acid to form salts and water are called bases.

Two examples of the base are:

• Sodium hydroxide $\left(\mathrm{NaOH}\right)$
• Ammonium hydroxide $\left({\mathrm{NH}}_4\mathrm{OH}\right)$

Alkali:

• An alkali is that chemical substance whose dissolution in water results in the generation of hydroxyl ions $\left({\mathrm{OH}}^{-}\right)$.

Two examples of the alkali are:

• Potassium hydroxide,$\left(\mathrm{KOH}\right)$
• Sodium hydroxide $\left(\mathrm{NaOH}\right)$
