In summary: I was getting tired.In summary, the conversation discusses the possibility of creating a liquid metal-based anti-freeze using Mn and KMnO2. There is a debate over whether KMnO2 will stay in an aqueous state and the potential effectiveness of a metal suspension in preventing freezing. There is also confusion over the difference between a metal-ion compound and a metal and the best way to create a liquid metal anti-freeze.

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
 

FAQ: Making a metal based anti-freeze

What is anti-freeze and why is it important?

Anti-freeze is a liquid substance that is added to a vehicle's engine cooling system to lower the freezing point of the coolant. This prevents the coolant from freezing and causing damage to the engine during cold temperatures.

How does metal-based anti-freeze work?

Metal-based anti-freeze works by using metal particles, such as copper or aluminum, to lower the freezing point of the coolant. These particles act as nucleation sites for ice crystals, preventing them from forming and allowing the coolant to remain liquid at lower temperatures.

What types of metals are commonly used in metal-based anti-freeze?

Copper and aluminum are the most commonly used metals in metal-based anti-freeze. Copper is preferred for its effectiveness at low concentrations, while aluminum is used for its lower cost and availability.

What are the benefits of using metal-based anti-freeze over traditional ethylene glycol anti-freeze?

Metal-based anti-freeze offers several benefits over traditional ethylene glycol anti-freeze, including better heat transfer, longer lifespan, and higher thermal stability. It also does not contain toxic chemicals, making it safer for the environment.

Are there any potential drawbacks to using metal-based anti-freeze?

While metal-based anti-freeze is generally considered safe and effective, it can cause corrosion in certain types of engines if not used properly. It is important to carefully follow the manufacturer's instructions and to regularly check and maintain the coolant levels in your vehicle.
