Question

Name the following:
Name two bases which are not alkalis i.e insoluble bases

Answer 1

Hint: Bases are the chemicals which are going to react with the acids and neutralize them by forming salts. Few bases are also called alkalis and they are soluble in water. But all bases are not alkali in nature.

Complete answer:
- In the question it is asked to write the names of the two bases which are not alkalis and they are not soluble in water.
- We know that the bases like sodium hydroxide are strong bases and it is soluble in water.
- Then the sodium hydroxide is a strong base and is going to act as a good alkali.
- But asper the question we have to find two bases but they are not supposed to act as alkali and they are insoluble in water.
- We know that all alkali are bases but all bases are not alkalis.
- The chemicals like copper hydroxide and aluminum hydroxide are the chemicals and are basic in nature.
- But copper hydroxide and aluminum hydroxide are not soluble in water.
- So, the bases which are not soluble in water are not going to act as alkali.
- Therefore, copper hydroxide and aluminum hydroxide are the bases but they are not alkali.

Note:
The elements from the s-block are going to form bases very easily and the respective hydroxides are going to be soluble in water and they are going to act as an alkali. Potassium hydroxide is alkali and going to be used in so many chemical reactions.
