This article throws light upon the four types of electrode used in electrochemical techniques. The four types of electrode are: (1) The pH Electrode (2) Ion Selective and Gas Sensing Electrodes (3) The Clark Oxygen Electrode and (4) The Leaf Disc Electrode. Type # 1. The pH Electrode: Principles: Perhaps the most convenient and accurate way of determining pH is [...]

Buffers: pH, Capacity and Ionic Strength! pH: The negative logarithm of the hydrogen ion concentration, the pH, is expressed as follows: pH = -log10[H+] The pH scale is a measure of hydrogen ion concentration that eliminates dealing with large powers of 10 and compresses a large range of concentrations onto a more convenient scale, between 1 and 14. At a [...]
