| 41. | The reaction yields sodium sulfate ( Na 2 SO 4 ) and gaseous hydrogen chloride ( HCl ).
|
| 42. | Any equipment handling hydrogen chloride gas must be checked on a routine basis; particularly valve stems and regulators.
|
| 43. | Breathing in gas with more than fifty parts per million of hydrogen chloride can cause death in humans.
|
| 44. | From these experiments Priestley is credited with discovering many new gases such as oxygen, hydrogen chloride, and ammonia.
|
| 45. | Anhydrous hydrogen chloride reacts preferentially at the disubstituted alkene, whereas epoxidation with mCPBA occurs at the trisubstituted alkene.
|
| 46. | The preparation of tosyl esters and amides are conducted in the presence of a base, which absorbs hydrogen chloride.
|
| 47. | This method is used primarily with aromatic compounds under basic conditions in order to neutralize the resulting hydrogen chloride.
|
| 48. | Hydrogen chloride gas produced by a reaction of salt with sulfuric acid is then used to recover crystals for purification.
|
| 49. | For instance, hydrogen burns in chlorine to form hydrogen chloride with the liberation of heat and light characteristic of combustion.
|
| 50. | Different ways to make these salts include treating a metal chloride with anhydrous fluorosulfuric acid which releases hydrogen chloride gas.
