no, compressed water does not come out to be ice. ice is a less dense crystallization of water in which the shape of the water molecules form a specific pattern. you can envision H2O as a V shape with the tops of the V being the hydrogen and the bottom being the oxygen. with the hydrogen slanted off to the sides like that, it creates a non-neutral charge on one side of the oxygen that is overcome at temperatures above 4degrees celsius by the heat motion of the atoms. under 4 degrees celsius the exposed charge on the oxygen atom starts making the molecules restructure their shape until, temperature dropping, it turns to a crystalline form - ice . water is less dense than ice because when its heat temperature is enough to overcome the attraction the V shape of the molecule allows the gaps of the structures to be filled in... well, when you compress water where you'd occasionally have gaps due to various misaligning of the V shape you would get molecules that would press together and condense into more nooks and crannies of the molecules. so basically, no. compressing water does NOT turn it into ice.
sodium acetate would still be a salt even to ~320C. that's when it decomposes. When it is not dissolved, it is in a solid state. When you dissolve it, it is aqueous. The temperature of the solution has no impact on whether or not it is a 'salt' or not. An aquoues solution is NOT the same thing as a 'liquidized salt'.

That's not ice, sorry.

Crystallization is an exothermic process. Boiling is an endothermic process.

The sledge hammer coming down would heat up the air, my point is that it quickly cools again since it is an adiabatic process.
