Molisch’s Test is a sensitive group test used regularly to detect all carbohydrates in free or combined form. Monosaccharides react rapidly, whereas disaccharides and polysaccharides react slowly. Principle: This test uses concentrated H2SO4 to catalyze the dehydration of sugars to … Read more
The iodine test is used to differentiate polysaccharides from monosaccharides and disaccharides. The Iodine Test is a simple yet effective chemical method used to detect the presence of starch and other substances. It relies on the reaction between iodine and … Read more
Benedict’s test detects reducing sugars (sugars having a free reactive carbonyl group). It is a qualitative chemical test that detects reducing sugars in a given sample. Reducing sugars possess a free aldehyde or ketone functional group and can reduce other … Read more
This procedure involves digestion and distillation. The soil is digested in concentrated H2SO4 with acatalyst mixture to raise the boiling temperature and promote the conversion from organic-N toNH4-N. The NH4-N from the digest is obtained by steam distillation, using excess … Read more
