An amorphous solid 'A' which has a crown shaped structure, burns in air to form a gas 'B' which turns lime water milky. 'B' is also produced by roasting of sulphide ores. 'B' undergoes oxidation in the presence of V_(2)O_(5) to give 'C' and to carry out this oxidation low temperature and high pressure is mandatory to get a good yeild of 'C'. 'C' is then absorbed in H_(2)SO_(4) to give 'D'. 'D' is then diluted to give a very important. 'E' in concentrated form, when combined with Cu metal, gives compound 'F'. From this description Give two important functions of 'E' in the chemical industry.
