red blood salt is a crystal of potassium ferricyanide.This compound is synthesized in vitro and used in the chemical industry.Incidentally, this substance is known in the world, and under another name - hexacyanoferrate (III) potassium.
red blood salt and its properties
potassium hexacyanoferrate is an artificial crystal of monoclinic structure.Blood salt has a distinctive deep red color, which is reflected in its title.
crystals are transparent, translucent in the presence of light.Interestingly, the larger the crystal, the more saturated the color becomes.The substance is not oxidized under the influence of air, but perfectly soluble in water to form an orange or green-yellow solution.Weathering potassium hexacyanoferrate occurs only when heated.
by reaction with acid forms a toxic substance.That is why the red blood salt is considered a strong poison.When injected into the digestive system of a substance reacts with stomach acids.For human lethal dose is approximately four grams.
red blood salt and its application
Potassium ferrocyanide is used in the production of various kinds of electrical engineering.Furthermore, solutions of substance used in the process of development images.
The aqueous solution of this tool has found a use in the chemical industry.There it is used as a reagent for detection of iron ions.
Blood salt is also used in pyrotechnics.Sometimes it produces hydrogen cyanide.
Rules storage of red blood salt
Since the substance is highly toxic, and it must be handled with extreme caution.The crystals must be protected from exposure to acids, water and steam.Since the heating agent starts eroding, it is necessary to protect it from exposure to high temperatures.Potassium ferrocyanide should be stored at a temperature no higher than forty degrees Celsius.
Do not expose the crystals prolonged exposure to direct sunlight.And another important point: after work with the substance to be thoroughly wash your hands.
yellow blood salt and its properties
yellow blood salt - this is another fairly well-known substance, which is a yellow transparent crystals.
This material is known by other names, such as geksatsianoferat (II), potassium, yellow sinkali.The history of the generic name like yellow blood salt.The fact that at the time it was prepared by fusion with potash and iron filings blood and other waste from slaughterhouses.
This material gradually erodes in the air, so the crystals are usually coated with a thin layer of protective varnish.Substance well diluted in water to form solutions of a bright yellow color.When heated, it begins the process of weathering.As with the previous item, the yellow salt is toxic to the human body as quickly reacts with gastric acid to form a heavy toxins.
Therefore, crystals and storage conditions are similar - do not expose them to water, acids, moisture, and sunlight.
use ferrocyanide
This material is widely used in modern industry.For example, the salts of the pigments produced.Certain derivatives yellow salt used in dyeing textile fabrics, in particular silk.
Yellow salt is widely used in analytical chemistry for the detection of ions in the solution of various substances.For example, the reaction with the salt of ferric ions precipitate formed very characteristic entitled "Prussian Blue".In conjunction with zinc salts obtained white precipitate.And during the reaction with cuprum turns reddish-orange solid.
