acid anhydride react with water
Acid Anhydrides react with water to form carboxylic acids.22 jan. 2023
Will adding water to an acid anhydride generate an acid?
' Acid anhydrides are non-metal oxides that can react with water to form acidic solutions.
Important acid anhydride reactions include the reaction of water vapor with sulfur trioxide and carbon dioxide.
Base anhydrides are Group I and II metal oxides that can react with water to form basic solutions.
What happens when acetic anhydride reacts with water?
Aqueous solutions have limited stability because, like most acid anhydrides, acetic anhydride hydrolyses to give carboxylic acids.
In this case, acetic acid is formed, this reaction product being fully water miscible: (CH 3CO) 2O + H 2O → 2 CH 3COOH.
What happens if acetic anhydride gets wet with water?
Permanent opacification can occur if decontamination is delayed.
Acetic anhydride reacts with water to form acetic acid.
