Question
Give two uses of HCl.

Answer

Hydrogen chloride (OR hydrochloric acid) is used :
  • in the manufacture of chlorine and ammonium chloride,
  • to manufacture glucose from com, starch
  • to manufacture dye
  • in mediClne and galvanising
  • as an important reagent in the laboratory
  • to extract glue from bones and for the purification of bone black.
  • for dissolving metals, $Fe + 2HCl_{(aq)} \rightarrow FeCl_2 + H_{2(g)}$
