Barium is an element, derived primarily from the mineral barite, and used as a heavy additive in oil-well-drilling mud, paints, rubber, plastic and paper; production of barium chemicals; and glass manufacturing.ercury is extracted from the mineral cinnabar and is used in electrical products, electrolytic production of chlorine and caustic soda, paint, and industrial and control instruments (thermometers and thermostats). Mica. Mica minerals commonly occur as flakes, scales, or shreds.
If the electronegativity difference is between 0 and 0.2, it is a nonpolar covalent bond. If the electronegativity difference is between 0.2 and 1.4, it is a polar covalent bond. If the electronegativity difference is greater than 1.4, it is an ionic bond. Calcium is 1.3, Chlorine is 3.0, for a difference of 1.7. Calcium Chloride is an ionic compound.
Calcium chloride can serve as a source of calcium ions in an aqueous solution, as calcium chloride is soluble in water.This property can be useful for displacing ions from solution.For example, phosphate is displaced from solution by calcium:he anhydrous form of calcium chloride may also be used for this purpose and can provide a measure of the moisture in concrete. Calcium chloride is used in swimming pool water as a pH buffer and to adjust the calcium hardness of the water.
