In Molischs test it dehydrates sugar into hydroxy methyl furfural (from hexoses)/furfural (from pentoses) which would then condense with alpha-naphthol to give The OH group of sugar is eliminated in the form of water when monosaccharides are treated with concentrated H 2 SO 4 or concentrated HCl, and What is the significance of the steps involved. The formation of a purple ring is a positive indicator for Molischs Test. A positive reaction for Molischs test is given by almost all carbohydrates (exceptions include tetroses & trioses). Statistical significance is used in hypothesis testing, whereby the null hypothesis (that there is no relationship between variables) is tested.
