measure nitric acid in sulphuric acid

Hot concentrated nitric acid oxidises sulphur to sulphuric acid. Sulphur is further oxidised by the nascent oxygen to sulphur trioxide. Sulphur trioxide then combines with water to form sulphuric aci..

Sulphur dioxide reduces hot concentrated nitric acid to nitrogen dioxide, a reddish brown color gas. Adding equations (i) and (ii), we get..

Aqueous nitric acid obtained by this method can be concentrated by distillation to 68.5% by mass. Further concentration to 98% acid can be achieved by dehydration with concentrated sulphuric acid. Anhydrous nitric acid can be ob..

Johann Glauber (1604-1668) prepared nitric acid by heating nitre with concentrated sulphuric acid and then condensing the vapour. While Henry Cavendish determined the composition of nitric acid, Lavoisier proved that oxygen is present in h..

Nitric acid can be prepared by distilling a mixture of a nitrate salt with concentrated sulphuric acid. As nitric acid is a volatile acid it can be expelled by a stronger but less volatile acid such as concentrated ..

The important uses of nitric acid are as follows: 1) Nitric acid plays a significant role in the manufacture of various products such as: Explosives like trinitrotoluene (T.N.T.) nitro glycerine, gun cotton, ammonal etc. Fertilizers such as calcium nitra..

The most important and useful oxoacid of nitrogen is nitric acid. Its molecular formula is HNO 3 and molar mass 53 g mol - 1..

Chemical Properties of Sulphur - With Acids - Sulphur does not react with hydrochloric acid. Dilute sulphuric acid and dilute nitric acid also do not affect sulphur..

Uses of Sulphuric acid - In the manufacture of fertilizers, ammonium phosphate and calcium super phosphate. In the manufacture of rayon and nylon and also in the preparation of dyes and drugs from coal tar derivatives. In the manufacture of the explosives such as Tri-nitro tolue..

Uses of Sulphuric Acid - 1) In manufacture of fertilizers Sulphuric acid is used in the manufacturing process of fertilizers such as ammonium sulphate, super phosphate of lime, etc. 2) In chemical industry It has a wide variety of use in the chemical industry..
