Cobalt chloride hexahydrate, also known as cobalt chloride (hexahydrate),hexahydrate cobalt (II) chloride, etc., is an inorganic compound with a red or purple red monoclinic crystal structure. It is easily deliquescent, soluble in water, acetone, and ethanol, and slightly soluble in ether. It is stable at room temperature, but begins to weather at temperatures above 30-35 ℃. When heated to 110-120 ℃, it completely loses 6 crystal waters and becomes anhydrous hexahydrate. Its aqueous solution turns blue when heated or with concentrated hydrochloric acid, chloride, or organic solvents. The solution also turns blue when exposed to light and quickly returns to its original color in humid air. Due to its toxicity, inhaling hexahydrate dust can sometimes lead to bronchial asthma. For sensitive individuals, inhaling hexahydrate dust can cause obstructive pulmonary disease and symptoms such as shortness of breath. Dust is irritating to the eyes and long-term exposure can cause eye damage. When 500 milligrams of hexahydrate enter the body within a day, it can cause loss of appetite, vomiting, diarrhea, and redness of the face and limbs. Grinding hexahydrate can cause acute dermatitis, with a large number of scattered red papules and small nodules, edema, and sometimes ulceration on the surface. Excessive intake can cause acute poisoning, leading to damage to the blood, thyroid, and pancreas. It is used in electrolytes for tin plated cobalt alloys and cobalt nickel phosphorus alloys, and can also be used as an additive for zinc plating, chemical cobalt plating, and cobalt alloys. Manufacturing cobalt catalysts. hexahydrate test paper is blue when dry and turns pink when wet, and can be used to indicate the moisture absorption level of silica gel. Used for coloring glass and ceramics. Used as a paint drying agent, ammonia absorbent, invisible ink, etc.

Frequently Asked Questions
What are the extremely obscure "art history" applications of its iconic "color changing" characteristic beyond industrial humidity indication?
+
-
In medieval manuscript illustrations and Victorian era floral paintings, its dilute solution was used as invisible ink or special blue/green glass pigments. The deep blue color that appears after being dehydrated by heat, fades back to light powder after cooling and absorbing moisture, creating a "mysterious appearance" effect.
Apart from HIF-1 induction, what is an easily overlooked "chemical interference" in cell experiments?
+
-
It is a direct source of divalent cobalt ions. Cobalt ions can non specifically displace zinc/iron in the active centers of zinc and iron containing enzymes (such as certain DNA repair enzymes), leading to enzyme inactivation. This can cause false positive DNA damage or apoptotic signals, which can be misinterpreted as specific pathway activation.
Why was it used as a "foam stabilizer" in the beer industry, but it almost disappeared later?
+
-
In the 1960s, it was found that it could significantly improve the cup hanging durability of beer foam (by enhancing the complex of polypeptide isohumulone). However, the outbreak of "beer drinkers' cardiomyopathy" caused by cobalt toxicity (in Quebec, Canada, patients who drank 10-30 bottles per day experienced heart failure and cardiogenic shock) led to the global ban of this use in the 1970s.
What "cold" standards for specific metal impurities are implied behind the purity requirements (98-102%) for ACS grade reagents?
+
-
This is one of the most stringent trace impurity controls in reagent grade. For example, the limit for copper (Cu) is 0.002%, the limit for nickel (Ni) is 0.01%, and the limit for zinc (Zn) is 0.005%. This is much higher than the ordinary "industrial grade" or "chemically pure" standards, with the aim of absolutely avoiding interference from trace transition metal contamination on sensitive catalytic or analytical systems.
Why is there a completely opposite literature description of the "deliquescence" and "weathering" behavior of its powder or crystal?
+
-
This is the key obscure knowledge about its phase transition characteristics. At room temperature and moderate humidity, hexahydrate (CoCl2 · 6H2O, pink) will undergo weathering, losing some crystalline water and transforming into tetrahydrate (purple red). But at low temperatures or extremely high humidity, it will instead deliquescence, and the surface will adsorb water to form a saturated solution film. Therefore, the storage conditions (Argon charged) are extremely strict.
