Receiving potassium acetate and its property
Potassium acetate has an appearance of the white or colourless crystals having alkalescent taste. Crystals are very hygroscopic and in the open air under the influence of water vapor they quickly enough blur. On air crystals are practically not dissolved, but well rastvorima in water with formation of solution of potassium acetate.
On the toxicity potassium acetate corresponds to acetic acid. Has the expressed preserving properties thanks to which prevents development of pathogenic fungi and bacteria.
Potassium acetate as was already told, is salt of acetic acid. Therefore it is received as a result of interaction of hydroxide or potassium carbonate with solution of acetic acid. Reaction of receiving potassium acetate can be written down so:
K2CO3 + 2CH3COOH = 2 CH3COOK + H2CO3
The carbonic acid received as a result of this reaction is the unstable substance which is almost instantly decaying on carbon dioxide and water. Therefore an end product of reaction is aqueous solution of potassium acetate, having evaporated which it is possible to receive pure substance in the form of crystals.
Potassium acetate use
In the food industry crystals and solution of Kalii acetas are used as preservatives and regulators of acidity. At long storage acidity of any product begins to change. For prevention of it potassium acetate which is called E-261 nutritional supplement is also used.

Potassium acetate is used also in pharmacology. It is a part of some diuretic medicines. In addition thanks to the ability to decay on bicarbonates and at the expense of it to reduce the general level of acidity, solution of Kalii acetas is applied in complex therapy of diabetic ketoacidosis.
Also potassium acetate is widely used in the textile industry and by production of forages for farm animals.
Influence of potassium acetate on a human body
It is authorized to use potassium acetate as nutritional supplement without any restrictions only in Ukraine and in Russia. In all other countries of Europe and in the USA this substance is considered not safe and therefore its use is sharply limited.
