Acetate

Sodium acetate forms white crystals in powder form.

Chemical Formula: CH₃COONa

Layman's explanation: Sodium acetate is known for its ability to supercool. It freezes at 130 degrees, but can exist as a liquid at a much lower temperature. In order to melt solidified sodium acetate, however, every single crystal must liquify, otherwise the material will recrystallize. Sodium acetate has been used as a deicer for roads and runways. It is also used a component of buffer systems. The compound is quite stable. It may act as an irritant and be harmful if inhaled or absorbed through the skin.

Keywords: supercoolant, deicer, stable
