Introduction: Determine the Enthalpy Change in Hydration of Anhydrous Magnesium Sulfate (MgSO4)

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.

    Shaken - it would help to post the maths in this, and maybe an explanation as to why people do these experiments?

    I will do this later on, and I found the simplfied version of calculation seems to be the best.

    Sodium acetate might be a good one to play with - it's reasonably popular stuff?

    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.

    Correct me if I'm wrong here, but the most interesting thing about magnesium sulphate (aka Epsom salts) is that they "go through you like a dose of salts" - i.e. they are a purgative?
