It is inserted in the apparatus set-up between the reaction container and the gas collection system. It is packed with a solid water absorbing drying agent e.g. anhydrous calcium chloride (not for ammonia), calcium oxide (not acidic gases like sulphur dioxide, carbon dioxide and chlorine), anhydrous sodium sulphate.
Nitrogen dioxide. Nitrogen dioxide is the chemical compound with the formula NO 2. It is one of several nitrogen oxides. NO 2 is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year.itrogen dioxide (NO 2) gas converts to the colorless gas dinitrogen tetroxide (N 2O 4) at low temperatures, and converts back to NO 2 at higher temperatures. The bottles in this photograph contain equal amounts of gas at different temperatures. Nitrogen dioxide is toxic to humans when inhaled.
