Acid Anhydride vs. Basic Anhydride: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 5, 2023
Acid Anhydride is a non-metal oxide that forms an acid when combined with water. Basic Anhydride is a metal oxide that forms a base when reacted with water.

Key Differences

Acid anhydrides are chemical compounds derived from acids by removing water. When they react with water, they form an acid. Basic anhydrides, in contrast, are compounds formed by removing water from a base. They react with water to form a basic or alkaline solution.

Structurally, acid anhydrides often consist of non-metallic elements and are associated with volatile organic acids. They are typically used in synthesizing acetic acid in industries. Basic anhydrides, on the other hand, are composed of metallic elements, common in compounds like calcium oxide. They are often used in making basic solutions like lime water.

In terms of reactivity, acid anhydrides react vigorously with water, alcohols, and amines to produce acidic compounds. These reactions are crucial in producing esters and amides. Basic anhydrides are less reactive than their acidic counterparts but still react with water and acids, neutralizing them to form salts and water.
