Importance of slowly heating hydrates
Witryna25 mar 2012 · We noticed that during the hydrate growth the steady state temperature inside the reactor vessel has a small but noticeable dependence on the nature of sediment, viz., it is around 278 K for pure methane hydrates & those with silica particles (50, 150 and 250 μm) 279 K. WitrynaStudents remove the water of crystallisation from hydrated copper(II) sulfate by heating. Condensing the vapour produced in a second test tube collects the water. The white anhydrous copper(II) sulfate is then rehydrated and the blue colour returns. This experiment can be carried out in pairs by students. It should take no more than 30–40 ...
