Question

(ii) An example of base which is not a alkali is
(iv) An example of acid salt is
(v)An acid having basicity 1 is ​

Answer 1

Answer:

Explanation:

Some bases such as sodium hydroxide, potassium hydroxide are also called as alkali because these bases are soluble in water. Whereas bases such as copper hydroxide, zinc hydroxide, silver hydroxide are not alkali because we know that these bases are insoluble in water. Hence, they cannot be called alkali.

So sodium bisulphite is an acidic salt. . It is formed by reacting the carbonic acid with the sodium hydroxide.

Hydrochloric acid (HCl) is formed from one H+ ion and one Cl− ion. Then it has one replaceable hydrogen and its basicity is one.

Answer 2

Answer:

(ii)Some bases such as sodium hydroxide, potassium hydroxide are also called as alkali because these bases are soluble in water. Whereas bases such as copper hydroxide, zinc hydroxide, silver hydroxide are not alkali because we know that these bases are insoluble in water. Hence, they cannot be called alkali.

(iv) NaHSO3 is an acidic salt. It's anion can act as an acid by giving up one more proton and so it is acidic in nature.

(v)Hydrochloric acid

Hydrochloric acid (HCl) is formed from one H+ ion and one Cl− ion. Then it has one replaceable hydrogen and its basicity is one.
