Anhydride means to remove a water molecule H2O from the original compound. KOH has only 1 oxygen and 1 hydrogen atom. Therefore, 2 KOH formula units are required to complete the removal--> 2KOH has to subtract 2 H and 1 O from its formula and will finally give K2O
hence, the anhydride of KOH is K2O
Formula for anhydride of the base LiOH is:
Li2O
"Subtracting water" 2LiOH--H2O + Li2O
This oxide is La2O3.

Maleic Anhydride.
Trifluoromethanesulfonic anhydride = (CF3SO2)2O
RaCO3 is a salt

Maleic Anhydride.
Trifluoromethanesulfonic anhydride = (CF3SO2)2O
An anhydride is not an acid and not a base.
An anhydride is a compound formally derived from another by the loss of a water molecule.
It use to reduce the part of phthalic anhydride
RaCO3 is a salt
Nitric acid does not form the anhydride but dinitrogen penta oxide is theoretical anhydride of nitric acid.2HNO3 = N2O5 + H2O==========No. From the Wikipedia article on nitrogen pentoxide:N2O5 was first reported by Deville in 1840, who prepared it by treating AgNO3 with Cl2.Therefore, nitrogen pentoxide is the anhydride of nitric acid.
The product of the reaction between anthracene and maleic anhydride is known as anthracene-maleic anhydride adduct. This adduct is commonly used in the synthesis of dyes, polymers, and other organic compounds.
