Chemistry

An anode is an electrode of a polarized electrical device through which conventional current enters the device. It is the positive part of electrolytes where

A solution in which the solvent is water. is called an aqueous solution. It is mostly shown in chemical equations by appending (aq) to the

A cathode is the electrode from which a conventional current leaves the electrolyte. It is the negative part of the cell where reduction takes place.

Cations are positively charged ions (atoms or groups of atoms that have more protons than electrons due to having lost one or more electrons). Cations

An atom, with a valency of two, which thus can form two covalent bonds is called divalent. For example, oxygen (O), magnesium (Mg), etc. have

Electrodes are conductors, in the form of wires, rods or plates, through which current enters and leaves the electrolyte. When the current leaves the electrodes

An electrolyte is a substance that dissociates in water into charged particles called ions. Positively charged ions are called cations. Negatively charged ions are called

An electrovalent or ionic bond is formed when a metal atom transfers one or more electrons to a non-metal atom. Ionic or electrovalent compounds are
