RaCO3 is a salt composed of the metal cation Ra2+ and the carbonate anion CO32-. It is neither an acid nor a base, but rather a salt.
acid anhydride
An anhydride is not an acid and not a base.
The anhydride of Triflic acid is Trifluoromethanesulfonic anhydride (Tf2O). It is a powerful electrophilic reagent used in organic synthesis for esterifications and acylations.
Nitrogen pentoxide (N2O5) is the oxide of nitrogen that is also referred to as a mixed anhydride because it can act as both an anhydride and an acid anhydride in chemical reactions.
An anhydride is a compound formally derived from another by the loss of a water molecule.
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.
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 compound name for salicylic acid is 2-hydroxybenzoic acid, and for acetic anhydride it is ethanoic anhydride.
Ethanoic anhydride can no longer be oxidized by any oxidizing agent.
An acid anhydride is an organic compound that has two acyl groups bound to the same oxygen atom. Usually, the acyl groups come from the same caboxylic acid, he formula for the anhydride being (RC(O))2O + H2O
Phthalic anhydride is sparingly soluble in methanol. Even though it can dissolve in methanol to some extent, it is not highly soluble and forms a suspension or a cloudy solution rather than a clear, homogeneous one.
