In chemical cold packs, solid ammonium chloride dissolves in water forming aqueous ammonium and chloride ions. As a result of this solvation reaction, the pack feels cold on your injured ankle. In chemical hot packs, solid sodium acetate crystallizes from a supersaturated solution of sodium acetate. The pack feels warm to the touch for 30 ...

Nov 10, 2017 · Ammonium Chloride Ring. Description: Vapors of ammonia and hydrochloric acid diffuse towards each other inside a tube. A ring of ammonium chloride forms where the two chemicals meet and react. Concept: The ratio of diffusion rates of two gases is equal to the square root of the inverse of the ratio of their molecular weights.
