An aqueous solution of glucose reacts concentrated sulphuric acid to give compound

Concentrated sulphuric acid is:

Dehydrating cane sugar with concentrated sulphuric acid

Concentrated sulphuric acid is not used to dry hydrogen.

Addition of water to concentrated sulphuric acid is an ____reaction.

A solution of a salt in concentrated sulphuric acid H_(2)SO_(4) acid produced a deep blue colour with starch iodide solution.The salt may be

(i) An organic compound A with molecular formula C_(7)H_(8) on oxidation by chromyl chloride in the presence of C Cl_(4) gives a compound B which gives positive Tollen's test. The compound B on treatment with NaOH followed by acid hydrolysis gives two product C and D. C on oxidation gives B which on further oxidation gives D. the compound D on distillation with sodalime gives a hydrocarbon E. Below 60^(@)C , concentrated nitric acid reacts with E in the presence of concentrated sulphuric acid forming a compound F. identify the compounds A,B,C,D,E and F. (ii) Give chemical test to distinguish : Formaldehyde and acetaldehyde.

Phenol, when it first react with concentrated sulphuric acid and with concentrated nitric acid, gives

Give Reaction of potassium chlorate with concentrated Sulphuric Acid .

An aqueous solution of concentrated hydrobromic acid contains 48% HBr by mass. If the density of the solution is 1.50g//L , what is its concentration :

Hydrogen chloride gas is prepared in the laboratory using concentrated sulphuric acid and sodium chloride. Answer the question that follow based on this reaction : Why is concentrated sulphuric acid used instead of concentrated nitric acid ?
