the interval shown here represents a

weak acid
strong acid
weak base
strong base

The pH scale was given by Sorensen to quanitatively define strength of an acid and base

the pH scale extends from 0 to 14

For acids

The pH should be less than 7 [always]

For base

The pH should be more than 7 [always]

The pH seven is of neutral solution

pH = -log[H+]

Thus lower the pH higher the concentration of hydronium ion or protons produced by an acid

thus for the given pH scale interval [0-3] it represents strong acid [Which will give high concentration of protons on dissociation]

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it
