The reaction between acetic acid and sodium hydroxide belongs to acid-base neutralization reaction, which produces sodium acetate and water.
Sodium acetate, also known as sodium acetate, is a colorless and odorless crystal, which can be weathered and combustible in the air. Soluble in water, slightly soluble in ethanol, insoluble in ether.
Acetic acid is widely distributed in nature, such as fruits or vegetable oils, but mainly exists in the form of esters. It exists in animal tissues, excreta and blood in the form of free acid. Many organisms can convert different organic substances into acetic acid by fermentation.
Extended data:
Sodium hydroxide can be completely dissociated into sodium ions and hydroxide ions when dissolved in water, so it has the universality of alkali. ?
It can react with any protonic acid for acid-base neutralization (also a metathesis reaction);
NaOH + HCl = NaCl + H？ O
2NaOH + H？ So what? =Na？ So what? +2H？ O
NaOH + HNO？ =NaNO？ +H？ O
Silicon will also react with sodium hydroxide to generate hydrogen, for example:
Si + 2NaOH + H？ O=Na？ SiO？ + 2H？ ↑
The preparation of aluminum hydroxide also involves the use of sodium hydroxide:
6NaOH +2KAl (so? )? =2Al (oh)? ↓ + K？ So what? +3Na？ So what?
Note: Al(OH)? Aluminum hydroxide is a colloidal coagulant, which is usually used to remove impurities from water. Because the hydroxides of transition metals are mostly insoluble in water, and the surface area of aluminum hydroxide is large enough to adsorb small particles, alum (KAl(SO? )? 12H？ O) Transition metals can be precipitated in the form of hydroxide, and the preliminary filtration of tap water can be completed by using simple filtration equipment.
Aluminum hydroxide can be used to prepare alum (KAl(SO? )? 12H？ O) dissolving aluminum hydroxide in sulfuric acid, adding metered potassium sulfate solution, heating for reaction, filtering, concentrating, crystallizing, centrifugal separation and drying to obtain the finished product of potassium aluminum sulfate.
Most acetic acid is synthesized by methyl carbonylation. In this reaction, methanol and carbon monoxide react to produce acetic acid, and the equation is as follows.
CH？ OH + CO →CH？ Wow!
This process is completed in three steps, and the intermediate is methyl iodide, which requires a multi-metal catalyst.
