2.6 Water Solubility Slightly soluble in water. Insoluble in alcohol.3. Use and Manufacturing3.1 Description CALCIUM SULFIDE, with the chemical formula CaS and CAS number 20548-54-3, is a chemical compound. It appears as a yellow to brownish-yellow solid with a rotten egg-like odor. The ba...
soluble in water, barium hydroxide is easily soluble in water. Calcium sulfide has the lowest alkalinity, strontium sulfide is in the middle, and barium sulfide has the strongest alkalinity. Barium sulfide hair removal is more effective than calcium sulfide. Due to the toxicity of barium sulfide,...
calcium carbonate an insoluble salt occurring naturally in bone, shells, and chalk; used as an antacid, calcium supplement, and phosphate binder, and for treatment of osteoporosis. calcium channel blocker (calcium channel blocking agent) a drug such as nifedipine, diltiazem, or verapamil that select...
If the glass contains lead and/or barium oxide, the glass should be treated with a mixture of hydrofluoric and sulfuric acids and the insoluble lead and barium sulfates filtered off before the titration. Lead may also be precipitated with hydrogen sulfide. Small amounts of aluminum and iron may...
Chemical propertiesIt appears as white cubic crystalline powder. Industrial products often contain magnesia, alumina and ferric oxide and other impurities so exhibit dark gray, light yellow or brown. It is soluble in acid. Uses1. Calcium oxide can be used in the manufacture of calcium carbide, ...
Nickel compounds are categorized as water-soluble or water-insoluble (poorly soluble), or alternatively grouped as soluble, sulfidic and oxidic Ni [7]. Indeed, the toxicological profile appears to differ substantially between these groups. When, for example, soluble nickel sulfate (NiSO4), green ...
The production of oxalic acid by fungi provides a means of immobilizing soluble metal ions, or complexes, as insoluble oxalates, decreasing bioavailability and conferring tolerance (Sayer and Gadd, 1997). As mentioned earlier, most metal oxalates are insoluble, some exceptions being Na, K, Li ...
sulfide or hydroxide, preferably of 5-20wt% concentration, is brought into contact with the outer wall of a vessel filled with a heat-storing material containing calcium chloride hexahydrate to form a white, water-insoluble precipitate, whereby the leakage of the heat-storing material is detected...
crystal known as calcite, and orthorhombic form, aragonite. Calcite decomposes on heating at 825°C, aragonite melts at 1,339°C (at 102.5 atm). Density 2.71 g/cm3 (calcite), 2.83 g/cm3 (aragonite); insoluble in water (15mg/L at 25°C); Ksp 4.8x10–9 ; soluble in dilute mineral ...
