This is a video about how to determine the Enthalpy of hydration, I take Magnesium sulfate as an example to illustrate how it is determined. Hydrated MgSO4 and Anhydrous MgSO4 is dissolved seperately and temperature change is recorded, DeltaH of Anhydrous MgSO4 - DeltaH of Hydrated MgSO4 = Enthalpy of hydration.

Shake<strong>n</strong> - it would help to post the maths in this, and maybe an explanation as to why people do these experiments?<br /> <br /> L<br />
I will do this later on, and I found the simplfied version of calculation seems to be the best.<br />
Sodium acetate might be a good one to play with - it's reasonably popular stuff?<br /> <br /> L<br />
It is not reasonably popular stuff, it is extremely popular indeed! I considered to film about it, but I got other project to do, so maybe later.<br />
Correct me if I'm wrong here, but the most interesting thing about magnesium sulphate (aka Epsom salts) is that they &quot;go through you like a dose of salts&quot; - i.e. they are a <em>purgative?<br /> </em><br /> L<em><br /> </em><br />
It is what you said, purgative!<br />
