Potassium sorbate is the potassium salt of sorbic acid, chemical formula CH 3 CH=CH−CH=CH−CO 2 K. It is a white salt that is very soluble in water (58.2% at 20 °C). It is primarily used as a food preservative (E number 202). [4] Potassium sorbate is effective in a variety of applications including food, wine, and personal-care products.
Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste. Potassium chloride can be obtained from ancient dried lake deposits. [7]
Potassium benzoate (E212), the potassium salt of benzoic acid, is a food preservative that inhibits the growth of mold, yeast and some bacteria. It works best in low- pH products, below 4.5, where it exists as benzoic acid.
It is a colorless salt, similar in appearance to sugar, that is highly soluble in water. Most KCN is used in gold mining, organic synthesis, and electroplating. Smaller applications include jewellery for chemical gilding and buffing. [4] Potassium cyanide is highly toxic, and a dose of 200 to 300 milligrams will kill nearly any human.
The low solubility of KClO 3 in water causes the salt to conveniently isolate itself from the reaction mixture by simply precipitating out of solution. Potassium chlorate can be produced in small amounts by disproportionation in a sodium hypochlorite solution followed by metathesis reaction with potassium chloride: [7] 3 NaOCl → 2 NaCl + NaClO 3
If a person is a stickler for measuring, Sergentakis recommended adding 10 grams of salt per liter of cooking water. Unlike others, he is not necessarily a fan of the "salty as the sea" adage.
The supposed superiority of bactericidal agents over bacteriostatic agents is of little relevance when treating the vast majority of infections with gram-positive bacteria, particularly in patients with uncomplicated infections and noncompromised immune systems. Bacteriostatic agents have been effectively used for treatment that are considered ...
They are also used to eliminate both free chlorine and the more stable form, chloramine, from water solutions (e.g., drinking water from municipal sources). Campden tablets allow the amateur brewer to easily measure small quantities of sodium metabisulfite, so they can be used to protect against wild yeast and bacteria without affecting flavour.
