Potentiometric Titrations

Potentiometric titration is one of the important titration methods and is mainly carried out to characterize acid solutions. It follows a method similar to that of the normal titration technique, but the main difference is that there is no indicator used in the potentiometric titrations. Instead of using an indicator, electrodes are employed for monitoring the whole titration process. A scientist named Robert Behrend did the potentiometric titration for the first time, and it was done using the mercurous solution and potassium chloride.

02:21 4G File Details 4CH003/UM1: Fundamentals of... Introduction Perhaps the cleanest method of conducting an oxidation is by catalytic oxidation, since this minimizes the problem of removal of unwanted by- products. However, the conditions used are often vigorous and require the use of specialized equipment. By comparison, the product of a "chemical" oxidation may be more difficult to purify due to the presence of the reduced form of the oxidizing agent and potential "tars" that may arise from "over- oxidation". Because chemical oxidation can be carried out using conventional equipment they are more popular. dissolving sodium or potassium dichromate in acid is a commonly used oxidizing agent, being classed as a relatively powerful oxidant and having water soluble by-products (Cr III salts). Sulphuric acid is generally used if the material to be oxidized is water soluble and glacial acetic acid is used if it is Chromic acid, prepared in-situ by not. Alcohols are readily oxidized to…
