Alkalis are water soluble bases.

So both bases and alkalis react with acids and neutralise them, but only alkalis are water soluble. All alkalis are basic but not all bases are alkalis.
In chemistry, an alkali is a basic, ionic salt of an alkali metal or alkaline earth metal chemical element. An alkali also can be defined as a base that dissolves in water.
Not all bases are alkalis. The most general definition is a Lewis Base, which is any compound that can accept a proton.
A Lewis acid is therefore any substance, such as the
The Lewis acid-base theory explains why
It can use the empty
The Lewis acid-base theory can also be used to explain why nonmetal oxides such as
