Ferric
Ferric (pronunciation: /ˈfɛrɪk/) is a term often used in chemistry to describe iron in its +3 oxidation state. It is derived from the Latin word ferrum, meaning iron.
Etymology
The term "ferric" comes from the Latin ferrum, which means iron. The "-ic" suffix is derived from the Latin "-icus", which is used in chemistry to denote a higher oxidation state.
Definition
Ferric refers to iron in its +3 oxidation state. In this state, iron has lost three of its electrons. Ferric compounds are usually brown or yellow in color and are often used in the manufacture of pigments and inks. Ferric ions can also be found in a variety of biological systems, including the human body, where they play a crucial role in processes such as oxygen transport and DNA synthesis.
