    Ph Solids
AI Thread Summary
The discussion centers on the inquiry about pH testers specifically designed for measuring the pH of solids, with a focus on an application involving dental health and caries detection. Participants clarify that measuring pH directly in solids is not feasible; instead, pH measurements are relevant for aqueous solutions that interact with the solid. The original poster seeks recommendations for purchasing a pH tester suitable for their project, but the conversation highlights the misunderstanding of measuring pH in solids versus solutions.

Hello everyone,

First of all thank you for your help.

I'd like to know if there are any ph testers for solids not diluted and where can I buy them and how much would they cost.

Thanks!

What does the pH of a solid mean? A measure of the pH only makes sense for an aqueous solution.

I'm studying a project in which we are trying to measure the ph of a tooth in order to detect a carie. That's why we'd like to get a ph tester for solids
 
Ok, so you're not measuring the pH of a solid, but the pH of a solution coating the solid.

I can't help you further, but hopefully some others can.
 
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!!
