Solubility product constant (K sp) (or the solubility product) is the product of the molar concentrations of the constituent ions, each raised to the power of its stoichiometric coefficient in the equilibrium equation.For instance, if a compound A a B b is in equilibrium with its solution DATE OF LAST REVISION: 06/18/15. Cadmium Sulfide courtesy of ahpmat.com. The solubility of cadmium sulfide in water (pH = 7) is found to be: 7.9. The shapeless form of cadmium sulphide is yellow, orange or brown. Not available. Cadmium sulfide is also soluble in 3 M HCl and in hot, dilute \(\ce{H2SO4}\). It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite, but is more prevalent as an impurity substituent in the similarly structured zinc ores sphalerite and wurtzite, which are the major economic sources of cadmium. Cadmium sulfide is a yellow solid. Cadmium Sulfide Distributor of cadmium sulfide. Cadmium oxide easily decomposes and dissolves in nitric acid which has not been diluted too much. When it is made for pigment, the cadmium sulfide is then washed, heated (to change it into the right form), and ground to a powder. Environmental Science & Technology 2013 , 47 (22) , 12775-12783. Filtration, centrifugation, ultracentrifugation, and dialysis were used to separate the particles from the solution. Solubility.
