    Mineral, Mineral - Mineral - Hardness: Hardness (H) is the resistance of a mineral to scratching It is a property by which minerals may be described relative to a standard scale of 10 minerals known as the Mohs scale of hardness The degree of hardness is determined by observing the comparative ease or difficulty with which one mineral is scratched by another or by a steel toolBarium, Barium compounds are notable for their high specific gravity - which, in practical terms, means the compounds are extremely heavy This is true of the most common barium-bearing mineral, its sulfate - barite BaSO 4 - is called 'heavy spar' due to the high density (45 g/cm³ - the size of a pea)GRAVIMETRIC ANALYSIS, A certain barium halide exists as the hydrated salt BaX 22H 2 O, where X is the halogen The barium content of the salt can be determined by gravimetric methods A sample of the halide (02650 g) was dissolved in water (200 cm 3) and excess sulfuric acid added The mixture was then heated and held at boiling for 45 minutHardness of tap water samples in Manila City, Philippines ,, Dec 01, 2017· Information regarding the total hardness of water in the Philippines is not published or not made readily available , Minor contributors to the total hardness of water include other polyvalent ions, such as aluminum, barium, iron, manganese, strontium, and zinc , The presence of these sedimentary rocks and other factors that contribute to ,Interpretating a Water Analysis(1), Very small concentrations of barium can cause serious barium sulfate scaling problems because barium sulfate scale is not soluble in most oil field scale dissolving chemicals Barium content is used to calculate barium sulfate scaling tendenci Barium content can range from very low (1 - 10 mg/l) to 1,000 -2,000 mg/l Strontium (Sr).
