Because the acetate in the sodium acetate solution is a weak electrolyte, it will combine with some hydrogen ions when dissolved in the water, which will produce some free hydroxide ions, destroying the original neutrality, thus making Sodium acetate solution is alkaline overall.

Sodium acetate, also known as sodium acetate, is an organic substance with a molecular formula of CH3COONa and a molecular weight of 82.03. Sodium acetate trihydrate is a white crystal with a relative density of 1.45 and a melting point of 58°C. It weathers in dry air, loses crystal water at 120°C, and decomposes at higher temperatures.

Anhydrous sodium acetate is a colorless transparent crystal with a melting point of 324°C. Easily soluble in water, it can be used as buffer, mordant, determination of lead, copper, nickel and iron, medium preparation, organic synthesis, film printing, etc.

Used as buffering agent, flavoring agent, flavoring agent and pH adjuster. As a buffering agent for flavoring agents, 0.1-0.3 can be used to alleviate bad odors and prevent discoloration to improve flavor. It has a certain anti-mildew effect. For example, 0.1-0.3 is used in minced fish products and bread.

It can also be used as a sour agent for sauces, sauerkraut, mayonnaise, fish cakes, sausages, bread, sticky cakes, etc. Mixed with methylcellulose, phosphate, etc., used to improve the preservation of sausages, bread, sticky cakes, etc.
