2014年6月19日 · In laboratory setting, is there a difference between glycerin and glycerol? There are some conflicting info on this topic.

2014年3月18日 · If the pKa of Glycerol is 14.15. How do you calculate the pH for it? I assume that the Henderson-Hasselbalch derivative that works for weak acids and bases is not applicable here.

2013年7月1日 · I boiled a solution of glycerol and water at about 160 degree Celsius and got a brown liquid much less in volume (boiled off the entire water I think; also not so sure about the accurate temperatur...

2015年7月6日 · I have come across the name trihydroxy propane for glycerol, which I think should've been Propan-1,2,3-triol. Why is it named this way? Is there any other rule of nomenclature working?

2021年6月11日 · Is the mixing of store-grade hydrogen peroxide 3% and glycerol in the ratio of 1:2 (V/V) at room temperature affecting the decomposition rate of hydrogen peroxide?

2020年1月22日 · From my school lab manual for identification of organic compounds: Take 2 ml of Tollens’ reagent and add a few drops of organic sample. Heat the contents on boiling water bath for 5 minutes. Silver mirror is formed. The given organic compound is glycerol. As far as I know, the compounds with aldehyde groups give positive silver mirror test.

I would like to know whether the reaction will take place if glycerol and citric acid are merged? In particular, what will happen if both substances are heated up to high temperature (+100°C)?

2016年2月24日 · With strong enough salt, the osmotic pressure causes water to flow out of the cell, so much that the cells dry up and aren't able to function. Water is miscible with glycerol, which makes glycerol an osmolyte. That means that glycerol would have the same effect as salt. Water mixed with glycerol is lower in concentration than pure water.

2021年3月1日 · Water and glycerol are completely miscible - no insolubility at all. According to the CRC Handbook, glycerol and diethyl ether are immiscible. Of course, water and ether are also immiscible, but there is some slight solubility, so you might …

2014年11月16日 · As titled, I wish to know if glycerol/glycerin is soluble in ethanol (not soluble, slightly soluble, very soluble)
