Question

Difference between Alkalis and Bases ( at least 3 points ).

Answer 1

A base is any substance that neutralizes acid. It may or may not be soluble in water. 

Those bases which are soluble in water are called alkalis. 

Thus an alkali is a water-soluble base. For example NaOH, KOH etc.

Alkali, as well as base neutralize acid, but we have observed that alkali produce OH⁻ ions in the water, whereas bases such as copper oxide and ferrous do not produce OH⁻ ions.

This is why it is said that all alkalis are bases but all bases are not alkalis.
