31. The infrared spectrum of hydrogen chloride gas shows rotational fine structure superimposed on the vibrational spectrum. 32. Examples of polar molecules include hydrogen chloride ( HCl ) and chloroform ( CHCl 3 ). 33. Treatment of high-silicon ferrosilicon with hydrogen chloride is the basis of the industrial synthesis of trichlorosilane. 34. Methyl isocyanate is usually manufactured by the reaction of mole of hydrogen chloride as a gas. 35. That means for example that hydrogen chloride is in fact a much stronger acid than hydrochloric acid. 36. Hydrogen chloride will react in a manner that is so slow that it is essentially synthetically useless.37. Hydrogen chloride is also a dangerous chemical.38. The hydrogen chloride gas bubbles off and was discarded to atmosphere before gas absorption towers were introduced. 39. P 4 O 6 reacts with hydrogen chloride to form H 3 PO 3 and phosphorus trichloride. 40. A different gas of comparable solubility in water, such as hydrogen chloride , can be used instead of ammonia.
