Interpretation Introduction

Interpretation:

The acid and the base among the two diagrams along with the reason for the difference in their properties is to be explained.

Concept introduction:

The ability of an acid to ionize describes the strength of the acid.

The strength of an oxoacid depends on the polarity of the $\text{O}-\text{H}$ bond. The polarity is dependent mainly on the electronegativity of the central atom present in the oxoacid. The more electronegative the central atom, the more is its acidic strength.

Metals $\left(\text{M}\right)$ have the tendency to lose an electron to form stable ions. Thus, they do not polarize $\text{O}-\text{H}$ bond, but can polarize $\text{M}-\text{OH}$ bond releasing ${\text{OH}}^{-}$ ions.
