animation of elecrolysis of aqueous sodium chloride

(due to its highly negative electrode potential). Instead, H + ions produced due to the self-ionization of water get reduced at cathod..

Introduction - Even in the sixteenth century chemists knew that by heating common salt and concentrated sulphuric acid together, hydrogen chloride could be prepared. The sodium sulphate salt obtained during the reactions studied intensively for its properties is called Glauber's..

It is based on the electrolysis of aqueous solution of sodium chloride. The products of electrolysis are sodium hydroxide, chlorine gas and dihydrogen ga..

Take about 25 ml of a vegetable oil such as castor oil or groundnut oil in a beaker. Add about equal volume of concentrated solution of caustic soda (sodium hydroxide) to it. Heat the mixture slowly with stirring until it boils and a creamy paste of soap is formed. Boil further for 10-15 ..

Suspensions consist of particles of a solid suspended in a liquid medium. Suspensions are systems with two distinct phases. The particles in suspensions are bigger than 100 nm to 200 nm across. The particles of a suspension may not be visible to the naked eye but are visible under a microscope. Sus..

In laboratory, dinitrogen is prepared by heating an aqueous solution containing equivalent amounts of ammonium chloride and sodium nitrite. ..

Following are the chief uses of ammonia: 1) Ammonia is used in the industrial preparation of nitric acid by Ostwald's process. 2) Fertilisers, such as ammonium sulphate, ammonium nitrate, ammonium phosphate, urea etc. are manufactured with the help of ammonia. 3) It is used in the manufacture of ot..

Direct or Substantive Dyes - These can be directly applied by immersing the cloth in a hot solution of the dye in water. They can be again classified into acid and basic dyes. Acid dyes are sodium salts of sulphonic acid and nitrophenols. They are used for dyeing animal fibers (..

Dissolution of different salts in water does not always result in neutral solutions. For example, aqueous solution of copper sulphate is acidic whereas aqueous solution of sodium acetate is basic and aqueous solution of sodium chloride for..
