AI Thread Summary
Determining the concentration of vegetable oil in dilute oil-water emulsions can be challenging, especially with aeration and gas bubbles present. The initial approach using density measurements was complicated by water vaporization and the difficulties of measuring dilute samples accurately. A suggested solution involves adding tetrahydrofuran (THF) or a mixture of ethyl acetate and ethanol to break the emulsion, which may facilitate a clearer analysis. Additionally, employing Karl-Fischer titration can effectively measure the water content in the diluted samples, providing a more accurate determination of the vegetable oil concentration.

I've been trying to determine the concentration of a vegie oil (0.9 g/mL) in dilute(~2,4 w%) oil-water emulsions that are badly aerated and with gas bubbles.

I tried the density method, weighing the samples and then vacuum suck them to rid the bubbles - in order to get an accurate volume reading. But then I realized that water was vaporizing a little. and the dilute samples make the determination really hard.

Is there a way that's fast and easy to do that? chromotography?

Please help me... on my knees...

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
