Hot Ice
vinigar:carbon, hydrogen baking soda: soduim acetate
Sodium acetate is an ionic compound. It is composed of sodium ions (Na+) and acetate ions (CH3COO-) held together by ionic bonds resulting from the transfer of electrons between the atoms.
http://www.instructables.com/id/Sodium-Acetate/ (but the soduim acetate will not be pure enough to make hot ice, ive tried it) go here for a good guide on how to make it
The solubility of sodium acetate trihydrate crystals is greater in hot water compared to room temperature water. This is because higher temperatures generally increase the solubility of most substances, allowing more of the solute to dissolve in the solvent.
Firstly, when sodium acetate (CH3COONa) solidifies, it does not form "ice". It just becomes solid. This happens when the sodium acetate is heated to about 100oC, then cooled below its freezing point. When a foreign substance with the same crystal structure as sodium acetate is introduced, or a nucleation centre is provided, the sodium acetate will warm up to its freezing point and freeze at its (supposed to be) freezing point.

Sodium Acetate is CH3COO- Na+. However, as it is a salt of strong base and weak acid it gets hydrolysed and the result is * CH3COONa=== CH3COO- + Na+ * H2O===H+ + OH- * CH3COO- + H+=== CH3COOH There is equilibrium in 2nd and third reaction in water and hence on the whole the solution gets basic in nature due to presence of free OH- ions as compared to H+ ions
a solid
It is Na2S
Not
Na2CO3
No, sodium is a metal.
