IMPORTANT:
All content here meant to be Educational,None of the above experiment should be repeated on your own.

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.

  • MgSO4+C3H8O yeeuh yeeuh. did i almost kill myself or what?

  • I cooked Epsom earlier, and mixed it with water to see what would happen, and nothign did, but when i got bored and mixed it wit alchohol, it got almost 110*F.

    Why? did i heat it to much and creat this Sulfur Trioxide biproduct? or is it normal.

    just wondering it was kinda wierd but cool

  • @Feligatre99 You're an idiot. This is a thermochemical experiment, if he didn't cover it up, his errors would have been huge.

  • i tried doing this experiment by mixing 0.1moles of CaCl2 with 100ml of water and i got no temperature change or heat released.

    there was nothing wrong with the thermometer but i did use tap water

    will tht make a difference?

    also where did u get tht value of -104kj/mol for MgSO4

  • I did this experiment in my Chemistry lesson last week also :D

  • Very nice video, and well presented! 5*

  • yes
