Question

Show ionically why (i) phosphoric acid, (ii) sulphuric acid, (iii) acetic acid are called acids?
​

Answer 1

Ionic representation of phosphoric acid, sulfuric acid and acetic acid.

Explanation:

• The main concept of importance is that those substance which gives out hydronium ions $(H_3O^+)$ or hydrogen ions $(H^+)$upon dissociation with water are considered as acids.

i) Phosphoric acid:

• When phosphoric acid is dissociated in the presence of water, the following reaction occurs:

$H_3PO_4+H_2O$⇔$H_3O^+ H_2PO_4^-$

• As it gives out hydronium ions, it is called as acids.

ii) Sulfuric acid:

• When sulfuric acid is dissociated in the presence of water, the following reaction occurs:

$H_2SO_4+H_2O$$\rightarrow H_3O^++HSO_4^-$

• As it gives out hydronium ions, it is called as acids.

iii) Acetic acid:

• When acetic acid is dissociated in the presence of water, the following reaction occurs:

$CH_3COOH+H_2O$⇄$CH_3COO^-+H^+$

• As it gives out hydrogen ions, it is called as acids.
