A couple question regarding the recommendation to bake calcium chloride in the oven at 400*F for an hour, in order to ensure that it's anhydrous...
1. Is this still a sound recommendation?
2. Should it cool to room temp before putting in a container?
3. If it must cool, is there any risk in it picking up moisture again from the air?
4. What type of airtight container is recommended? Just the screw top bottle it was purchased in?
5. How long before one should consider doing this again, to maintain calculation assurances?
Thanks!
