What chemicals are used in instant ice packs by michael hinckley updated march 13, 2018 when the ionic and non-ionic compounds come in contact, an endothermic reaction takes place which uses energy (in the form of heat) from the surrounding atmosphere, creating a cold sensation construction. This demonstration mixes two solids which react endothermically, taking in enough heat to freeze a wet block of wood to the flask the chemicals used for this reaction are barium hydroxide.

Research questions: how do cold packs work in chemistry, what happens during an endothermic reaction which substance cools off water the most: baking soda, sour salt, morton lite, washing soda, or a deicer. Instant hot and cold packs many instant hot and cold packs function by dissolving a salt into water as the salt disassociates, heat is either released in an exothermic reaction or absorbed in an endothermic reaction. Endothermic reactions are accompanied by the absorption of heat the dissolving of ammonium nitrate in water is an example of an endothermic reaction the solution resulting from this mixture is colder than either the ammonium nitrate or the water this is the simple explanation of what happens in an instant ice pack.

Instant ice packs are a good first aid solution to sprains, strains, and other minor injuries and thus are included in most first aid kits available today but the way that ice packs generate cold so quickly, or how they are able to be stored at room temperature for so long, often remains a mystery to most consumers. While the majority of commercial cold packs use ammonium nitrate or ammonium chloride, many types of salts create endothermic reactions instant cold packs maintain water and ammonium salt in separate sections, with a thin barrier in-between. Instant ice packs an instant cold pack is a device that consists of two bags one containing water, inside a bag containing ammonium nitrate, calcium ammonium nitrate or urea when the inner bag of water is broken by squeezing the package, it is allowed to dissolve the solid in an endothermic reaction this reaction absorbs heat from the surroundings, quickly lowering the pack's temperature.
