Electrogravimetry is the oldest electroanalytical technique in which the element of interest is deposited electrolytically onto an electrode and weighed. This article discusses the principles involved in determining the electrolysis rate of the solution, and describes different methods for the separation of ion in the electrolyte and their corresponding instrumentation. Furthermore, it explores the various types of analysis, such as the separation and quantitative determination of metal ions and internal electrolysis, and provides a detailed account of the applications of electrogravimetry with examples.

This article describes various methods of electrochemical analysis, namely coulometry, electrogravimetry, voltammetry, electrometric titration, and nanometer electrochemistry. The discussion covers the general uses, sample requirements, application examples, advantages, and limitations of these methods. Some of the factors pertinent to electrochemical cells are also provided. In addition, the article provides information on various potentiometric membrane electrodes used to quantify numerous ionic and nonionic species.

Electrogravimetry is a method used to separate and quantify ions of a substance, usually a metal. Quantification of these ions primarily depends on the rate of movement of charged species (ions) in an electric field. This article details the various types of electrometric titrations, namely, conductometric titration, oscillometric (high frequency) titration, potentiometric titration, amperometric titration, biamperometric titration, bipotentiometric titration, and coulometric titration. It also provides a brief outline of the applications of electrometric titrations.

This article focuses on wet chemical methods that have stood the test of time in laboratories around the world. It begins with a description of the appropriateness of classical wet methods. This is followed by sections on sampling procedures, basic chemical equilibria, and wet analytical chemistry. Mechanical methods and nonoxidizing acids and/or acid mixtures for dissolving solid samples for wet chemical analysis are then reviewed. Qualitative methods that are used to identify materials by wet chemical reaction are also included. The article provides information on various methods for the separation of chemical mixtures and on the types of gravimetry and titrimetry. Strategies for removing inclusions are also included to aid in their compositional understanding. The article also briefly describes the processes involved in chemical surface studies and partitioning of oxidation states. It ends by presenting some examples of the applications of classical wet methods.
