Titration Of Acids And Bases

Introduction According to Arrhenius definition, acid is substance that produces H3O+ ion while base is substance that produces OH- ions. The reaction between acid and base often yields the products of salt and water. The formation of water in this neutralization reaction is caused by the combination of H3O+ and OH- ions. In order to determine the concentration of an unknown acid and base, a method called acid-base titration is used. The end of the titration has been reached when…...

Perkin Reaction

Introduction: The name of this reaction is called the Perkin’s reaction. The reaction was first used by William Perkin to create phenylcinnamic acids (Johnson). It is very similar to the aldol condensation which is followed by elimination. In this reaction E and Z isomers of phenylcinnamic acid are created using benzaldehyde and acetic anhydride. The intermediate product is acetic phenyl acetic anhydride. Benzaldehyde is an aromatic compound that Results: The reaction involves the use of benzaldehyde with acetic anhydride which…...
