  • Chemistry Question How does this work?

    At the normal temperature reaction of acetic anhydride and CONCENTRATED sulphuric acid will result oxydation and destruction of acetic anhydride to carbon and carbon dioxide.

    How does this work , and is it right? Or does this statement seem more correct?

    Sulfuric acid reacts with acetic anhydride to form acetyl sulfate and Acetic acid.
