If heat is added, the equilibrium will shift towards the cobalt chloride complex, which is blue in color. Cooling will shift the products towards the hydrated complex, which is more pink. If the chloride or cobalt concentrations increase, the equilibrium will also shift towards the blue anhydrous cobalt chloride. What Read more…
Answer: The color of cobalt salt is blue. What is colour cobalt salt? The anhydrous form is a blue crystalline solid; the dihydrate is purple and the hexahydrate is pink. Commercial samples are usually the hexahydrate, which is one of the most commonly used cobalt compounds in the lab. What Read more…

It is made by incorporating cobalt oxide in the molten glass mixture. Most blue glass is given its color either from cobalt oxide or from copper oxide added to the molten glass. Copper is a more delicate colorant than cobalt. It only requires a small amount of cobalt oxide to Read more…
Cobalt chloride is a common visual moisture indicator due to its distinct colour change when hydrated. The colour change is from some shade of blue when dry, to a pink when hydrated, although the shade of colour depends on the substrate and concentration.

Cobalt (Co) is a bluish-gray, shiny, brittle metallic element. It has magnetic properties similar to iron. There are no significant minerals of cobalt. It is rare and obtained mostly through refining of nickel ore. How cobalt is mined? 98% of cobalt production is mined as a by-product Technologies include both Read more…
Cobalt chloride paper is an indicator of moisture. It is blue in colour when dry and pink coloured when moist. What does it mean if cobalt chloride paper turns pink? We know that the cobalt chloride turns from blue to pink under moist conditions. The change in colour indicates that Read more…
