AI Thread Summary
The discussion centers on the differences between pH meters used for measuring pH in solutions, creams, and oils. Participants emphasize the importance of conducting personal research before asking questions and suggest that pH measurement is primarily relevant for water-based mixtures. It is noted that pH meters may not be suitable for non-aqueous substances unless they contain water. The conversation encourages the original poster to share any findings from their research to foster a more productive dialogue.

ph meters for solutions, cream and oil.
Hello, can anyone advise about specified differences between ph meters for solutions, cream and oil.

To be honest, this looks like a spam setup post, but I'll play along for now.*

At PF, we require users to do their own research before posting questions here. So what have you found in your searching so far?

Maybe @berkeman made the right guess. Otherwise, did you try checking with merchants of pH meters? Is your question based on interest from your education, your experience, or a hoped-for application? I am strongly guessing that pH measurement would only have meaning for water-based blend or mixture or solution. Or maybe for some water dispersed in non-aqueous materials. Experts could respond.
 
So I googled the question and found an interesting article quite easily.
Let's wait to the OP tells us what research they have done first.
 
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...
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!!
