Sodium acetate, also known as sodium acetate, is a sodium salt derived from acetic acid. Sodium acetate is a substance that is easily made from vinegar and baking soda. When the mixture cools below its melting point, it will crystallize. Crystallization is an exothermic process, so these crystals actually generate heat, which is why this material is usually called hot ice. This compound has many industrial and everyday uses.

In the food industry, sodium acetate is used as a preservative and pickling agent. Because salt helps food maintain a certain pH value, it can prevent the growth of harmful bacteria. In the process of curing, this chemical must be used in large quantities. It can not only be used as a buffer for food and microorganisms, but also improve the taste of food.

As a cleaning agent, sodium acetate can neutralize a large amount of sulfuric acid discharged from the factory. It keeps shiny metal surfaces by removing rust and stains. In addition, it can also be found in leather tanning solutions and image processing solutions.

Sodium acetate also plays a role in the health industry. After dilution, it can be used as a salt solution to replace sodium chloride for intravenous injection. Although the risk of using sodium acetate is small, it is necessary to know the relevant knowledge. Sodium acetate must be diluted before being added into intravenous injection. The patient should receive the solution slowly to avoid water retention and electrolyte imbalance. For patients with kidney disease, aluminum in this solution may be toxic. Despite these risks, this solution is considered safe for all ages.
