Reusable hand warmers work by utilizing a chemical reaction that generates heat when activated. These hand warmers typically contain a mixture of iron powder, salt, water, and activated charcoal. When the hand warmer is exposed to air, the iron powder oxidizes, releasing heat in the process. This reaction can provide long-lasting warmth for several hours before the hand warmer needs to be recharged by boiling it in water to reset the chemical reaction.

Is sodium acetate in hand warmers?

Contained inside re-usable hand warmers is a super-saturated solution of sodium acetate. When a metal disk inside is bent, it forms a nucleation site for crystals. The supersaturated solution forms a crystaline hydrate, and releases heat in the process. The solution can be reformed by heating the crystaline hydrate.

How do non reusable hand warmers work?

Non-reusable hand warmers typically use a chemical reaction to generate heat. They contain iron powder, salt, water, and other ingredients sealed in a pouch. When the pouch is activated, oxygen from the air reacts with the iron powder, initiating an exothermic reaction that produces heat. This process continues until the reactants are exhausted, providing warmth for several hours.
