Anhydride
Anhydride (pronunciation: /ænˈhaɪdraɪd/) is a chemical compound derived by the removal of water from another compound. The term is derived from the Greek words 'an' meaning 'without' and 'hydor' meaning 'water'.
Etymology
The term "anhydride" comes from the Greek words 'an' (without) and 'hydor' (water), indicating its formation from the removal of water from a substance.
Types of Anhydrides
There are two main types of anhydrides: acid anhydrides and basic anhydrides. Acid anhydrides are formed by the removal of water from an acid, while basic anhydrides are formed by the removal of water from a base.
Acid Anhydrides
Acid anhydrides are formed by the removal of water from an acid. They are typically non-metal oxides that react with water to form acidic solutions.
Basic Anhydrides
Basic anhydrides, also known as base anhydrides, are formed by the removal of water from a base. They are typically metal oxides that react with water to form basic solutions.
