Question

All alkali are bases but all bases are not alkali, why? explain with examples.

Answer 1

Answer:

I think this is correct answer for your question

Bases may either be soluble or insoluble in water. Therefore, all alkalis are bases because they will all neutralize acids, but not all bases are alkalis because not all bases will dissolve in water. An example of an alkali is sodium hydroxide.

Answer 2

Alkalis are the bases which are soluble in water. So, of course all alkalis will be considered as base. But, bases are either soluble or insoluble in water.

Eg- Sodium hydroxide is a base and as it is soluble in water, it is also an alkali.

On the other hand, the Copper oxide is just a base as it is not soluble in water.
