Describe on Test of Acetic Acid or Cacodyl Oxide Test - QS Study
top logo

Acetic acid is treated with sodium bicarbonate till effervescence is ceased. The solution thus obtained is evaporated to dryness when a solid residue is obtained. The solid residue is treated with finely powdered arsenious oxide and the mixture is heated, then vapor of cacodyl oxide having a very offensive smell is given out.

Reaction of acetic acid with an alcohol will produce an ester (typically, sweet smelling). E.g., reaction with ethyl alcohol (with sulfuric acid present as catalyst and a desiccant to remove water produced) produces ethyl acetate, which is commonly found in nail polish remover and has a fruity smell.
