Sodium acetate is a type of salt derived from acetic acid, although it can also easily be created from combining baking soda and vinegar. It is also known as sodium ethanoate, and hot ice, because the crystallized mixture emits heat when forming.
One of the most common uses for sodium acetate is as a pickling agent and preservative in the food industry. The salt is effective in helping to prevent bacteria from forming, as it enables the food to maintain a specific pH content. It can also improve the flavor of food when used as a preservative in larger amounts.
Sodium acetate can also eliminate stains and rust, and this property means that it is often used to keep metallic surfaces bright and shiny. It is used in other industries, including photography, petroleum and rubber production, and can also be used to treat patients with low sodium levels or high blood acid.
