test sample:-10%aqueous solution of glycerol. 1) acrolein test:-heat 2 drops of undiluted glycerol with little solid potassium bisulphate (khso4) in a dry test tube cautiously at first and then more strongly. note the pungent odour of acrolein. 2) dunstan's test:-add drop by drop enough of 1% alcoholic solution of phenolphthalein to about 5ml of 0.5% borax solution to produce a distinct red colour Borax in glycerin from nail fungus. Used externally. It is necessary to moisten cotton wool or a bandage in a solution, apply it for about 15-20 minutes to the damaged nail. You can put a bandage on top, after the recommended time to remove. It is important to take precautions. From the nail fungus is applied as a solution in glycerin What is Dunstan's test , How can it use for test Glycerol ? When phenolphthalein is added to dilute cold solution of borax, a pink colour is produced. When glycerol is mixed in it, in cold, the colour disappears, but on heating colour reappears. It is a characteristic test of glycerol. This test is called Dunstan's test

,so it is Methanol ,so it is not methanol it may be glycerol CT. Borax test a)0.2 g borax + 5 ml water, dissolve + add 2-3 dps ph.ph (pink color) b) add 0.2 ml glycerol,shake pink color disappear & reappear on warming ,so it is glycerol Dunstan's test is used for identification of glycerol. Phenolphthalein drops in borax solution give pink colour. Addition of glycerol to this solution discharges pink colour in cold which however reappears on heating and again disappears on cooling.
