What happens when CoCl2 is dissolved in water?
CoCl2 (aq) —–> Co+2 (aq) + 2Cl- (aq) 0 1. 6 matches found for CoCl2, 6H2O . 6H2O to water, it dissolves to give Chloride ions and CobaltII ions in solution.
What color is aqueous CoCl2?
Anhydrous cobalt chloride (CoCl2) is blue but cobalt chloride hexahydrate (CoCl2, 6H2O) is purple. So an aqueous solution of CoCl2 is purple.
Does CoCl2 dissolve in water?
Water
Cobalt(II) chloride/Soluble in
Is cobalt chloride aqueous?
The red colour of an aqueous solution of cobalt chloride is attributed to the ion [Co(H2O)6] and the blue colour with the same substance in presence of concentrated hydrochloric acid to the ion [CoCl4]”.
Is CoCl2 a solid or aqueous?
Cobalt(II) chloride is an inorganic compound of cobalt and chlorine, with the formula CoCl2. It is a red crystalline solid.
What is the result when CoCl2 is dissolved in water?
Question: 4. When CoCl2 is dissolved in water, the resulting solution is pink because of the presence of only) octahedrally coordinated [CoCI(H20)s] coordination complexes. If concentrated hydrochloric acid (a source of Cl) is added to this solution, the following equilibrium is established.
Is CoCl2 soluble or insoluble?
Cobalt(II) chloride

Is an aqueous solution of CoCl2 acidic basic or neutral?
COBALT CHLORIDE acts as a weakly acidic inorganic salt, which is soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH’s of less than 7.0.
What happens when you add HCl to CoCl2?
Concentrated hydrochloric acid contains a large amount of chloride ions so Le Chatelier’s Principle tells us that adding this will cause the position of equilibrium to shift to the right producing green CuCl2−4 ions.
What formed when HCl was added to the CoCl2 How do you know?
The addition of HCl forms a blue chloride complex.
