Red blood salt is apotassium ferricyanide crystals. This substance is synthesized in artificial conditions and used in the chemical industry. By the way, this substance is known in the world and under a different name - hexacyanoferrate (III) potassium.
Red blood salt and its properties
Potassium hexacyanoferrate is an artificial crystal with a monoclinic structure. Blood salt has a characteristic rich red tint, which is reflected in its name.
Crystals are transparent, translucent if present.Sveta. Interestingly, the larger the crystal, the richer the color becomes. The substance is not oxidized under the influence of air, but it is perfectly soluble in water to form an orange or green-yellow solution. Weathering of potassium hexacyanoferrate occurs only when heated.
The reaction with acids produces toxicsubstance. That is why red blood salt is considered a strong poison. When released into the digestive system, the substance reacts with gastric acids. For a person, the lethal dose is about four grams.
Red blood salt and its application
Potassium hexacyanoferrate is used in the production of various kinds of electrical engineering. In addition, the solutions of substances used in the process of developing photographs.
An aqueous solution of this tool has found application in the chemical industry. Here it is used as a reagent for the detection of iron ions.
Blood salt is also used in pyrotechnics. Sometimes from it make hydrocyanic acid.
Terms of storage of red blood salt
Since this substance has a hightoxicity, then it must be treated with extreme caution. The crystals must be protected from acid, water and steam. Since the reagent begins to erode when heated, it is necessary to protect it from exposure to high temperatures. Potassium hexacyanoferrate should be stored at a temperature not higher than forty degrees Celsius.
Do not expose the crystals to prolonged exposure to direct sunlight. And one more important point: after working with the substance, be sure to wash your hands thoroughly.
Yellow blood salt and its properties
Yellow blood salt is another fairly well-known substance, which is a transparent yellow crystals.
This substance is known under othernames, for example, potassium hexacyanofert (II), yellow blue. The history of such a trivial name as yellow blood salt is interesting. The fact is that at one time it was obtained by fusing with iron filings and potash of blood and other waste from slaughterhouses.
Данное вещество постепенно выветривается на therefore, crystals, as a rule, are coated with a thin layer of protective varnish. The substance is well diluted in water, forming solutions of bright yellow color. When heated, the weathering process begins. Like the previous element, the yellow salt is poisonous to the human body, as it quickly interacts with gastric acids, forming heavy toxins.
Therefore, the storage conditions of crystals are similar - they can not be exposed to water, acids, moisture, sunlight.
Use of yellow blood salt
This substance is widely used in modernindustry. For example, coloring pigments are made from salt. Some derivatives of yellow salt are used in the textile industry in dyeing fabrics, in particular, silk.
Желтая соль широко применяется в аналитической chemistry for the detection in solution of ions of certain substances. For example, when a salt reacts with ferric ions, a very characteristic precipitate is formed called “Prussian blue”. When interacting with zinc, a white salt precipitate is obtained. And during the reaction with cuprum turns reddish-orange precipitate.
