The water-insoluble compounds can be changed to water-soluble salts by acids or light and oxygen; e.g aqueous suspensions of cadmium sulfide gradually photooxidize to soluble (ionic) cadmium. Thus, Fe(OH) 3, Al(OH) 3, Co(OH) 2 are not soluble. Variations in soil composition, such as the organic matter content of a soil, also affect the toxicity of heavy metals. Obviously both are true here, but the reason of insolubility must be HIGHER LATTICE ENERGY. The simple trend is true provided you include hydrated beryllium sulphate in it, but not if the beryllium sulphate is anhydrous. In general when dealing with compounds of the group II with F-because of the small radius of F-the lattice enthalpy is great and only the hydration energy released by the hydration of Be 2+ outweigh it thus making BeF 2 soluble while all the other fluorides formed with the group II elements are quite insoluble in water Iron Sulfide Powder is soluble in acid, can release hydrogen sulfide gas, and is insoluble in The following is a list of substances NIOSH considers to be potential occupational carcinogens.
