HSAB principle (i.e Hard and Soft Acids and Bases principle) was introduced by Ralph Pearson to explain the stability of metal complexes and the process of their reactions. R. G. … Read more
EDTA (Ethylene Diamine Tetraacetic Acid) is an organic reagent that is frequently used in the complexometric titration. It is a chelating ligand with two nitrogen and four carboxylic acids that … Read more
Ozone is a condensed form of oxygen with the molecular formula O3. German chemist C.F. Schonbein (1799–1868) was the first to recognize ozone in 1840, he recognized that the smell … Read more
Metal ion indicators are the organic compounds used in the complexometric titration. Different types of metal indicators are used for the different metal ions. These indicators are usually used to … Read more
Complexometric titration also referred to as Chelatometry, is a volumetric analytical technique in which the titration’s endpoint is established using a colored complex. This is the titration between the metal ion … Read more
Redox indicator is an organic compound that exhibit a change in color in both the reduced and oxidized states, or at various potential values. Depending on oxidation and reduction potential, these … Read more
Acid rain is the most serious environmental concern caused by air pollution. Lakes, streams, plants, and animals that inhabit these ecosystems suffer severe danger from acid rain. Rain that has a pH value … Read more
Fajan’s rules can be used to determine the tendency of ionic compounds to acquire covalent character as a result of polarization. K. Fajan studied the factors which introduced the covalent … Read more
Redox reactions involve a change in oxidation number or transfer of electrons. The standard solution is either oxidizing or reducing agent. The oxidation-reduction reaction that takes place between the analyte … Read more
