Oh dear, the tornado is still blowing.

@M.A.R. Maths you say?

Note: I am basing this answer on Japanese Mahjong rules; Chinese rules will probably lead to a different outcome. Tenhou, Chihou or Renhou hands must be valid hands, i.e. they must satisfy the requirement of having four groups of three and one pair; except for Chiitoi (seven pairs) and Kokushi M...

Q: Pyrolysis of calcium chloride dihydrate

Does the pyrolysis of $\ce{CaCl2 · 2 H2O}$ give $\ce{CaCl2 + 2 H2O}$ or $\ce{Ca(OH)2 + 2 HCl}?$

@M.A.R. Hi :)

@pH13-YetanotherPhilipp Busy procrastinating. You?

@Loong Done

@M.A.R. I'm trying to understand a lab exercise from our lab course for the bachelor students that I had to supervise this year

@pH13-YetanotherPhilipp That sounds terrible. Are you OK?

I'm tired, but else I am fine. It took us quite a while to understand what we see in the exercise to now more and more find out that I should have searched a little bit better before trying to understand it by myself. :D
However, the exercise is not as easy as it is suggested by the current manual and that is rather distracting.

However ... at least we found during the last month that the "newly" bought conductivity electrodes are not precise enough. :'D

Oh tell me about it

@pH13-YetanotherPhilipp Bah psssht, not precise enough in Germany?
