Step 1

pH of a given solution is used to determine the concentration of H+ ions in the given solution so as to determine its acidity or basicity.

Buffer solutions are the mixtures containing a weak acid and its conjugate base or they may also contain a mixture of a weak base and a conjugate acid. Say for example a solution of acetic acid and sodium acetate can also be regarded as a buffer. These solutions have the property to resist change in the pH of the solution even when very small amounts of strong base or a strong acid is added.
