This video demonstrates a number of test tube reactions. Test tube 1 (left) contain ethanol, test tube 2 contain Phenol, test tube 3 contains ethanoic acid and test tube 4 (right) contains 2 Hydroxybenzoic acid.

The first set of reactions demonstrates the pH with Universal indicator being added.

The second set of reactions demonstrates the addition of sodium carbonate.

The third set of reactions demonstrates the addition of Iron(III) chloride

The fourth set of reactions demonstrates the addition of Acidified Potassium dichromate.
