Synthesising the manufacture of ammonia and its salts. A)AMMONIA AND ITS PROPERTY.      Main uses of ammonia : Manufacture of fertilizers such as ammonium sulphate,ammonium nitrate,ammonium phosphate and urea. Manufacture of nitric acid in Oswald Process. Manufacture of synthetic fibre and nylon. Liquid ammonium is used as cooling reagent in refrigerators. Prevent coagulation of latex. Physical properties of ammonia: colourless gas pungent smell very soluble in  water Chemical properties of ammonia: Soluble in water form weak alkali channges moist red litmus paper to blue Reacts with acids to form ammoinium salts Process to produce ammonia gas: Manufactured through Haber Process. The raw materials are nitrogen gas and hydrogen gas. Nitrogen gas was obtained from the distillation of liquid air Hydrogen gas was obtained by:             the reaction of steam with coal(carbon) which is heated ...

WELCOME TO MY BLOG😊 CHAPTER 9-MANUFACTURED SUBSTANCE IN INDUSTRY. 9.1 UNDERSTANDING THE MENUFACTURED OF SULPHURIC OF ACID. A) Main use of sulphuric acid. →detergent,fertilisers,synthetic fibres,leather tanning,electrolyte in car batteries and paints. B) The process to producing sulphuric acid. Manufactured through the contact process . Involving 3 raw materials :sulphur,oxygen gas and water. Sulphur is available from fossil fuels and sulphide ores. The process was through 3 stages. phase1: Producing sulphur dioxide gas.          S ⁺ O 2 →S0 2 phase2: Convert sulphur dioxide gas into sulphur trioxide gas with presence: vanadium(V)oxide temperature (450°C) pressure (1 atm)          2SO 2 (g)  +O 2 (g) ⇋ 2SO 3 (g) phase3: Dissolving sulphur trioxide into concentrated sulphuric acid to formed oleum,          SO 3   +  H 2 SO 4 ⟶...
