Expert Solution
Step 1

Introduction:

The acid or base form after the losing or gaining a proton is called conjugate acid and conjugate base. Example: For HCl acid, conjugate base will be Cl-. Strong acid has weak conjugate base and weak acid has strong conjugate base

pH shows the acidity of the solution. It is defined as the negative logarithm of H+ ions.
