Sodium acetate is a kind of organic matter. Sodium acetate trihydrate is white crystal with a relative density of 1.45 and a melting point of 58℃. It is weathered in dry air, loses its crystalline water at 120℃ and decomposes at higher temperature. Anhydrous sodium acetate is colorless transparent crystal, melting point 324℃. Soluble in water.
Appearance:
Sodium acetate typically appears as a white, crystalline solid or powder.
Solubility:
It is highly soluble in water, with a solubility of approximately 1 g in 1.5 mL of water at room temperature. It is less soluble in ethanol and insoluble in ether.
Melting Point:
The melting point of sodium acetate is around 58 °C (136.4 °F). The trihydrate form has a higher melting point due to the presence of water molecules.
Density:
The density of sodium acetate is about 1.5 g/cm³.
Taste:
It has a mildly salty flavor, which is why it is sometimes used in food applications.
pH:
An aqueous solution of sodium acetate has a pH of around 7.0, making it neutral.
Buffering Capacity:
Sodium acetate is commonly used as a buffering agent in biochemical applications due to its ability to maintain a stable pH when mixed with acetic acid.
Reactivity:
Sodium acetate can react with strong acids to produce acetic acid and the corresponding salt. It can also react with strong bases to form sodium hydroxide and other products.
Dehydration:
When heated, sodium acetate can lose water and form anhydrous sodium acetate, which can further decompose at higher temperatures.
Thermal Properties:
Sodium acetate has a unique property known as supercooling, where it can remain liquid below its melting point. Upon disturbance, it crystallizes rapidly, releasing heat in an exothermic reaction.
Application:
In terms of metal content determination, sodium acetate is used for determination of lead, zinc, aluminum, iron, cobalt, antimony, nickel and tin. Complex stabilizer. Auxiliary agent of acetylation, buffer, desiccant, mordant.
In food industry, sodium acetate is used as buffering agent, flavouring agent, flavouring agent and ph regulator.
In rubber industry, sodium acetate is used as the sulfur external regulation of neoprene coking antiscorching agent, the dosage of general quality of 0.5. It can also be used as a crosslinking agent for animal glue.
In electroplating industry, sodium acetate used in alkaline tin plating to add, but for plating and electroplating process and has no obvious influence, not necessary. Sodium acetate is commonly used as a buffer, such as in acid galvanizing, alkaline tin plating and electroless nickel plating.
