AI Thread Summary
The discussion centers on finding a non-flammable, conductive liquid chemical. Suggestions include water with dissolved salts, strong acids, or bases, as well as liquid metals like mercury and gallium. Liquid metals are noted for their high conductivity and low viscosity, making them useful in applications like orientation switches. However, mercury is heavily regulated in the U.S. due to its toxicity and potential to amalgamate with other metals, which can lead to corrosion. The conversation also touches on the risks associated with using ionic compounds in water, as they can produce flammable hydrogen gas and degrade components.

Hi, I am not a Chem student but I have a few questions.

I am looking for a non flammable chemical that is also conductive.Liquid form preferred!
Multiple suggestions appreciated...

What about water with salts or strong acids or strong bases dissolved in it?
Among pure substances: a liquid metal (Hg, Ga or any other metal which can be melted; in case, low melting point alloys) liquid HF, liquid ammonia.
 
What sort of application are you looking at? Water with an ionic or polar covalent compound dissociated in it it can cause redox reactions to occur (especially if you have non-inert metal electrodes). This can cause the creation of flammable hydrogen gas (with oxygen as an accelerant) and it can degrade components.

I agree with lightarrow that a liquid metal is handy. Mercury is used in some orientation switches because of its low viscosity and high conductivity.

This guy has a cheap indium and gallium liquid metal alloy if you are interested:

In the USA, mercury is banned from most or all retail products due to the toxicity of methyl mercury.
Mercury can amalgamate other metals (e.g., silver, gold, copper) and corrode others (e.g., aluminum).
About 1950, I panned lots of mercury near abandoned mercury mines in California (mercury was used to make primer during WW II), and have given most of it away.
 
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!!
