AI Thread Summary
The discussion centers on the formulation of a liquid metal-based antifreeze, specifically exploring the use of manganese (Mn) and potassium permanganate (KMnO2) to achieve an aqueous state. Participants clarify that KMnO2 is a metal-ion compound rather than a liquid metal and emphasize the importance of understanding solubility data. Concerns are raised about the potential for metal particles to clog systems like radiators and engine blocks, questioning the efficacy of a metallic suspension in lowering freezing points. The conversation highlights a need for clarity on the intended use and properties of the proposed antifreeze solution.

I'm trying to formulate an completely liquid metal-based anti-freeze.
I was thinking on using Mn, but I'm not sure whether it will stay in an aqueous state
After I adding KMnO2 to water to get the Mn in aqueous state.
Any help?

You mean metal-ion, not liquid metal. Mercury is a liquid metal.

Anyway, I'd suggest you go look up the solubility data in the CRC handbook or wherever.

But why do you want to do this? And why KMnO2 specifically?
 
I think you mean supspension of small particles of metal in a liquid medium. Metals have a nasty habbit of sticking to other metals and clogging things up, like the surface of radiators and engine blocks. Certain metalic suspensions are use to plug radiator leaks. Why do you want a metalic supsension?

Why would you think that? KMnO2 is a metal-ion compound, not a metal. (and 'aqueous' usually denotes the dissociated form if it's an ionic compound) A suspension of metal particles would have relatively little effect on the freezing point.

My mistake. It was getting late
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
