James Demers's latest activity
-
JFinally coming back to this... I dehydrated three different solutions in my oven set to 550°F: two were saturated solutions at 6.6 and...
-
JNote: there is always series of hydrates, differing with the number of water molecules, and getting to each next step requires higher...
-
JVery interesting. What I really want is a solution of consistent concentration that is as close to maximum concentration as reasonable...

JJames Demers replied to the thread Solubility of MgSO47H2O in water.As I noted above, you need to heat to about 500°F to remove all of the water of hydration.

JJames Demers replied to the thread Solubility of MgSO47H2O in water.MgSO4 is not volatile at all. The anhydrous salt is a white powder that is quite hygroscopic - chemists routinely use it to remove...

JJames Demers replied to the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it?.This is a bit of an over-simplification, but essentially you have 18 variables: 3 bodies x (3 velocity vectors + 3 coordinates)...

JJames Demers replied to the thread Solubility of MgSO47H2O in water.In reply to JT Smith: Most of the time, a chemist will be making up a solution having a desired concentration. This involves weighing...
