paper chromatography experiment: why should we tightly cover the beaker with aluminum foil?
You want to maintain a saturated vapor mixture within the beakerAlso, if you have a mixture of two solvents, the more volatile one would evaporate, and you really wouldn't get the separation you desireRemember, chemistry also depends on reproducibility, so if everyone doing the same experiment keeps their beakers covered, the results should be comparable.
Only a short term fix, and probably more calories that you don't need I suffer from this, and try and get 3 regular meals a day, drink about 2 litres of fluids Have oats and high fiber for breakfast Take coloxyl or coloxyl and senna for other days when I feel constipated works fine for me
I use coconut oil with my coffee it puts water in the bows also prunes and MiraLaxMy medicine and thyroid constipate me so bad.The laxatives took potassium and magnesium out of the body so, my doctor wanted me to try more natural things.I spend a arm and a leg on these things but they do work the problem is daily.I have not had a laxative since I started using these things.I do eat a fiber bar Kroger brand with caramel.This does help also but a lot of calories and carbs.Get Virgin,organic cold pressed coconut oil you will learn ho much you need me about a T a day of coconut maybe a little more just play with it.Lost of water I prefer c.Good luck.
