How can you determine anhydrides of acids and bases?

Answer 1

Well, the #"acid anhydride"# is simply two equiv of the parent acid LESS a water molecule...........

Thus, the anhydride of two equivalents of acetic acid is acetic anhydride:

#"2H"_3"CC(=O)(OH)"rarr"H"_3"CC(=O)(O)C(=O)(CH"_3) + "H"_2"O"#

Additionally, the term "base anhydride" is older and pertains to inorganic chemistry; that is, it describes two equivalents of the hydroxide LESS water:

#2NaOH rarr Na_2O + H_2O#

#"Natrium oxide"# is the base anhydride of #"sodium hydroxide"#.

Anhydrides of acids can be determined by observing their reaction with water, which will form the corresponding acid. Anhydrides of bases can be determined by reacting them with water, which will form the corresponding base. Additionally, anhydrides of acids can be identified by their characteristic acidic properties, such as turning blue litmus paper red, while anhydrides of bases may exhibit basic properties, such as turning red litmus paper blue.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
