Extracting Sodium Hydroxide from Soap

AI Thread Summary
Extracting sodium hydroxide (NaOH) from liquid soap is a topic of interest, particularly for testing purposes. It is noted that a solution derived from soap may primarily consist of a mixture of NaOH and potassium hydroxide (KOH), making it challenging to differentiate between the two due to their chemical similarities. Spectroscopy is suggested as a potential analytical method for distinguishing between these bases. However, if KOH is absent in the soap, testing for NaOH directly in the dissolved soap might be a more straightforward approach, eliminating the need for extraction.

is it possible to extract sodium hydroxide from liquid soap? i need to test the sodium hydroxide. if it is possible, how would i do it?

A solution of bases extracted from soap will probably end up primarily as a mixture of NaOH and KOH. As Borek mentioned, it's not really possible to tell the difference between different bases, especially in this case since potassium and sodium in solution are so chemically similar to each other. The only way I can think of differentiating between the two analytically is through spectroscopy.
 
qalomel, there is no koh in this soap
 
If there's no KOH and assuming that there aren't any other bases aside from NaOH in the soap, can't you just test the NaOH directly in dissolved soap without extracting it?
 

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!!

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...
