pH of a salt of a Weak acid and Weak base: Derivation

The above ppt will display a brief derivation of pH of a salt of a weak acid (WA) and weak base (WB) however this is helpful only if basic concepts and terminologies are clear.

2. WhatispH?
•pHis defined as the negative logarithm of H
+
ion concentration. Hence the meaning of the name pH is
justified as the power of hydrogen.
•Mathematical definition of pH states that the pH equals the negative logarithmic value of the
concentration of hydrogen ion (H+)
pH = -log [H+]
•Solutions having a value of pH ranging 0 to 7 on pH scale are termed asacidicand for the value of pH
ranging 7 to 14 on pH scale are known asbasicsolutions.
