CAN SOMEONE EXPLAIN WHY IS THE ANSWER CARBONIC ACID AND NOT PHOSPHORIC ACID?


Which of the following acids does not form acidic salts?
a-Phosphoric acid
b-Carbonic acid
c-Hydrochloric acid
d-Sulphuric acid​

Respuesta :

Carbon containing acids are week as it breaks down and form H+ ions .

Let's see

  • Take Carbonic acid.

[tex]\\ \sf\longmapsto H_2CO_3\leftrightarrow H^++HCO_3^-[/tex]

Hence it doesn't form acid salts instead it forms bicarbonate ions

Carbonic acid can not form an acid salt.

What is hydrolysis of a salt?

When a salt is dissolved in water, one or more of the ions in the salt does react with water. This reaction of the ions of the salt with water is what is called hydrolysis of a salt.

We have to note that when carbonic acid forms salts, we have a slt of the formula MHCO3 where M is the metal. Hydrolysis of this salt yields the bicarbonate ion which is basic.

Hence, carbonic acid can not form an acid salt.
