concentrated sulfuric acid has strong oxidizing property, oxidation of -1 valence of bromine to bromine, the release of red-brown gas, this method can be used to identify sodium iodide (sodium iodide and concentrated sulfuric acid heating, the release of purple gas), therefore, only concentrated...
0 2Concentrated sulfuric acid reacts with alkenes, alcohols and sodium halides.0 2.1Name the mechanism for the reaction of concentrated sulfuric acid with an alkene.[1 mark]0 2.2Outline the mechanism for the reaction of concentrated sulfuric acid with propene to show the formation of the major ...
This method can be used to identify sodium iodide (Heating sodium iodide and concentrated sulfuric acid together will release red-purple gases), Thereby, we can only take the concentrated phosphoric acid together with sodium bromine for heating to produce hydrogen bromine. Bromide ions can enhance ...
Hydriodic acid (H*I) is very unstable and decomposes very rapidly on exposure to light. It is thus frequently prepared in situ, from sodium iodide and phosphoric or sulfuric acid. It is often used in solution in glacial acetic acid, and reacts with alcohols to give the corresponding halides...
Catalysts which have been used for this latter reaction include concentrated sulfuric acid and methanesulfonic acid 〈80JCR(S)35, 75JOC2239〉. Aromatic ketones, however, preferentially undergo Baeyer–Villiger reactions and thus 3,3,6,6-tetraaryl derivatives are better prepared by ozonolysis of ...
While many people have tried their hand at anodizing aluminum at home, there are plenty who would just as soon leave it up to the professionals due to the highly concentrated sulfuric acid required for the process. [Ken] started thinking about the process and wondered if there was a wayto ...
Purification MethodsIt is recrystallised from a saturated aqueous solution (2.7mL/g) by passing in HCl gas, or by adding EtOH or acetone. It can be freed from bromide and iodide impurities by adding chlorine water to an aqueous solution and boiling it for some time to expel free bromine an...
315°C; decomposes on further heating; soluble in water, 28.6 g/100mL at 25°C; highly soluble in boiling water, 100g/100 mL at 100°C; aqueous solution strongly acidic, pH of 0.1 M solution 1.4; insoluble in liquid ammonia; decomposed by alcohol into sodium sulfate and sulfuric acid....
