How are strong alkali and weak alkali different? Give two examples for each of them.
Answers
Answer:
A strong acid or alkali is one that is nearly or completely ionised in water. Examples are: hydrochloric acid, nitric acid and sulphuric acid. Sodium and potassium hydroxide are examples of strong bases. A weak acid or alkali, on the other hand, is only partially ionised in water.
Explanation:
i dont know an example
Answer:
1. An alkali is a basic, ionic salt of an alkali metal or an alkaline earth metal. It is a base that dissolves in water.
2. A strong alkali is an alkali that is fully ionized in water to produce a high concentration of hydroxide ions (-OH). A weak alkali is an alkali that ionizes partially in water to produce a low concentration of hydroxide ions (-OH).
a) Strong alkali:-
An example of strong alkali is Sodium Hydroxide. A strong alkali has a pH of 14. It dissolves in water.
b) Weak alkali:-
An example of weak alkali is Ammonia, Barium Hydroxide. A weak alkali has a pH of 11 or 12. It partially dissolves in water.
