It is used in the manufacture of calcium fluoride. It is also used in the extraction of uranium.
- Solid calcium chloride is hygroscopic and is used as a drying agent. 1-Ammonia solution: No precipitates are formed because of their relatively high solubility. If the alkaline solutions are exposed to the atmosphere, some carbon dioxide is absorbed and a
Uses of Alkaline Earth Metals They are the constituents of alloy formation. Beryllium is used for manufacturing of parts of X-ray tubes. Magnesium-aluminum alloys are used for air craft construction.
2018/4/23· Due to low ionisation enthalpies, group II metals are strongly electropositive in nature. Electropositivity increases down the group from Be to Ba. alkaline earth metals when burnt in presence of oxygen produce flame color. Calcium, Strontium and Barium produce flame of brick red, crimson and apple green colors.
The alkaline earth metals are produced for industrial use by electrolytic reduction of their molten chlorides, as indied in this equation for calcium: Equation 21.22. CaCl2(l) → Ca (l) + Cl2(g) The group 2 metal chlorides are obtained from a variety of sources.
2020/5/3· Calcium is used in the extraction of metals from their oxides which are difficult to reduce with carbon. Calcium and barium metals due to their reactivity towards oxygen and nitrogen at elevated temperature have often being used to remove last traces of air from vacuum tubes. Radium salts are used in radiotherapy. About Mrs Shilpi Nagpal
