@ VIN why is CO2 needed for rusting???? Heard it for the first time in my  life ....

Not possible. It will make it Fe2O3C.xH20 something. It will cause rust to contain carbon...

Let's make it straight solubility will depend on the ionic strength of solutions. You need to learn what is polarity(which we dont have) umm example "Like compounds dissolve Like compound"

ethanol is an organic compound .. ions dont disassociate in ethanol


ionic compounds can only disassociate into water
