sulphuric acid acts as a dehydrating agent.all carbohydrates are dehydrated to give dehydration products. For example, pentoses give furfural as dehydration product where as hexoses give 5-hydroxy furfural.. these are attacked by 1-napthol to give a purple coloured condensation product...

What is the importance of Molisch's test performed on carbohydrates?
Molisch's Test is a chemical test for the presence of carbohydrates, based on the dehydration of the carbohydrate by sulfuric acid to produce an aldehyde. Its importance is that it tests the presence of carbohydrates based on their dehydration,
What is the composition of molisch test?
molisch reagent is prepared by dissolving 5g of alpha napthol in 100 ml alcohol
Why is molisch test used for brain lipid detection?
because there are such types of lipids that have carbohydrates attached to them(glycolipids). that's why Molisch test is used for lipid detection.
Why egg albumin gives the negative result for molisch test?
Molisch's test is used to detect carbohydrates. Egg albumen is free from carbohydrates.
What chemicals are used in the extraction of copper?
A strong acid such as sulphuric acid is used.

What is the purpose of Molisch's test?
Molisch's Test (named after Austrian botanist Hans Molisch) is a sensitive chemical test for the presence of carbohydrates, based on the dehydration of the carbohydrate by sulfuric acid to produce an aldehyde, which condenses with two molecules of phenol (usually α-naphthol, though other phenols (e.g. resorcinol, thymol) also give colored products) resulting in a red- or purple-colored compound.
What is molisch?
Molisch's Test refers to a chemical test used to test for carbohydrate existence. This is done using carbohydrate dehydration with hydrochloric or sulfuric acid to create aldehydes. These condense a couple phenol molecules to produce purple or red compounds.
What is the positive result for molisch test?
all carbohydrates show positive result to Molisch test. this is because Molisch test is used to distinguish carbohydrates from other organic compound.
Why is molisch test used for brain lipid detection?
because there are such types of lipids that have carbohydrates attached to them(glycolipids). that's why Molisch test is used for lipid detection.
Why egg albumin gives the negative result for molisch test?
Molisch's test is used to detect carbohydrates. Egg albumen is free from carbohydrates.
What is the general test used for carbohydrates?
i think the general test for carbohydrates is Molisch Test..
What is the action of sulphuric acid on red litmus?
Blue litmus is used to test acidic solutions.
Why is sulphuric acid not used in preparation of carbondioxidei?
because sulphuric acid stops reaction
What chemicals are used in the extraction of copper?
A strong acid such as sulphuric acid is used.
What can a sulfuric acid do and what is it used for?
Sulphuric acid is used in the manufacture of fertilisers (superphosphates) and as a battery acid.
