It can be inferred from its large negative reduction potential value, i.e., -2.84V. Reactivity towards AcidsД¬alcium, being an alkaline earth metal, readily react with acids to liberate dihydrogen.Д¬alcium is an excellent reducing agent. The formation of bubbles inside the water shows the formation of hydrogen gas, and cloudy white precipitation shows the formation of calcium hydroxide.Д¬alcium reacts with halogens (F, Cl, Br, I) upon heating and form dihalides.Д¬a(s) + F2(g) в†’ CaF2(s) (Calcium fluoride)Д¬alcium fluoride exists in nature as fluorite mineral. It also reacts with water vigorously, even in cold water, to form calcium hydroxide with the liberation of hydrogen gas. It is readily attacked by air to form calcium oxides and calcium nitrides, and hence, it is never found free.ДЈCa(s) + N2(g) в†’ Ca3N2(s) (calcium nitride) Reactivity towards Water The main reason behind the existence of calcium in combined form is that it reacts instantly with air. Chemical Properties Reactivity towards Air The melting point of calcium is 842вЊ, and its boiling point is 1484вЊ. Flame photometers are also available, which are used to estimate the concentration of calcium in the sample (during qualitative analysis). The detection of calcium element during qualitative analysis (academics related) is done through a flame test. Flame ColourД¬alcium imparts characteristic brick red colour when placed in the flame.

Biological role of Calcium in Human BodyД¬alcium is solid at room temperature, and as an alkaline earth metal, it possesses a silvery-white lustre and is a soft metal.ДЄlthough calcium is the fifth most abundant element in the earthвЂ™s crust, it is never found free in nature, and it is always found in a combined form, such as limestone (calcium carbonate), gypsum (calcium sulfate), fluorite (calcium fluoride), and apatite (calcium-phosphate mineral).
