Question

Magnesium hydroxide is a strong base. (True / False)

• A. True
• B. False

Answer 1

The correct option is B False

Alkalis:-

1. Alkalis are the basic and ionic salt of the alkali metals and it can also be known as the bases which dissolve in water.
2. Bases are actually the compounds which are able to accept the protons and donate the electrons.
3. Here, the Magnesium hydroxide $\mathrm{Mg}{\left(\mathrm{OH}\right)}_2$, is an alkali but a very weak one which is not completely soluble in water , it actually dissociates completely but will not get completely dissolved in water.
4. So, Magnesium hydroxide $\mathrm{Mg}{\left(\mathrm{OH}\right)}_2$ is a weak base, as it is less soluble in water.

Therefore, the above given statement ‘Magnesium hydroxide is a strong base’ is false.
