Acid Anhydride vs. Basic Anhydride: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Acid anhydrides are derivatives of acids that react with water to form acidic solutions, while basic anhydrides are oxides of metals that react with water to form basic solutions.
Key Differences
Acid anhydrides are chemical compounds derived from acids, typically by removing water, whereas basic anhydrides are metal oxides that react with acids. Both play crucial roles in chemical reactions, yet their natures and applications differ.
