Chemical properties of Ethanol & Phenol Objective To find out the chemical properties and pH of ethanol and phenol, and compare their differences between ethanol and phenol. Results Reaction of ethanol: Properties / Reactions Observations / Smell Corresponding equations (if any) pH of solution universal indicator remains green, pH=7 / Triiodomethane reaction yellow precipitate found at bottom of test-tube, with odour smell C2H5OH + 4I2 + 6NaOH › CHI3(s) + HCOO-Na+ + 5NaI + 5H2O Reaction with Na Na sinks to bottom, colourless gas, which gives a 'pop' sound to burning splint, evolves slowly and moderately. When ethanol-ethoxide mixture in test-tube is poured onto a petri-dish, small, colourless rectangular-shaped crystals are formed in a few minutes. 2C2H5OH + 2Na › 2C2H5O-Na+ + H2(g) Esterification When the mixture of ethanol, ethanoic acid & conc.H2SO4 in test-tube is poured into Na2CO3 solution, a smell like all-purpose adhesive is noticeable. Reaction of phenol: Properties / Reactions Observations / Smell Corresponding equations (if any) Solubility in water: (a) a little phenol ...
