iii doontnt knoww?
the salt starts to disintegrate
It dies.
explodes

well what happens is the engine doesn't work no more. Also you will have to replace the fuel pump.
Nothing. They're terrestrial.
The color of the flame depends on the metal from the salt.
The concentration of salt increase up to saturation.
It will ruin the engine. Ethanol is a much harsher fuel than gasoline and also requires a higher compression ratio to burn efficiently.
Salt cannot be "put in mercury" unless the salt is mechanically restrained. Mercury has a much higher density than salt and does not chemically react with it, so that salt will simply float on the mercury.
They die
It fizzes up and overflows.
