The lattice energy remains constant because sulphate ion is so large, so that small change in cationic sizes do not make any difference. Solubility in water is related to the ionic nature and size. The high solubility of BeSO 4 and MgSO 4 is due to the high hydration enthalpy because of smaller size of … Solubility of sulphates: The solubility of sulphates of alkaline earth metals decreases as we move down the group from Be to Ba due to the reason that ionic size increases down the group. Answer. Solubility — temperature diagrams were prepared for this temperature range. Even ignoring entropy (to a first approximation we might assume that the entropy change is constant for all the metals), solubility depends on both lattice energy and hydration enthalpy so you can't just look at one trend.

This paper presents studies on the crystallisation of alkaline‐earth metal tungstates, molybdates, chromates and sulphates by slow cooling of solutions in lithium chloride and alkaline‐earth metal chloride melts at 600° to 1100°C. Decomposition of nitrates: nitrates formed by alkali metals decompose evolving oxygen. Because BeO and MgO are much more inert than the other group 2 oxides, they are used as refractory materials in applications involving high temperatures and mechanical stress. 1.

Alkali metal sulphates are more soluble in water than alkaline earth metals. Beryllium ion is the most soluble and the solubility decreases with increasing size so that Barium ion is the least water-soluble alkaline earth metal ion. why are G2 elem called alkaline earth metals? Solubility of the alkaline earth metal sulphates in water decreases in the sequence. Log in. Share with your friends. 7 8 9. Hello! Hydroxides of the lighter alkaline earth metals are insoluble in water, but their solubility increases as the atomic number of the metal increases. Maths. Carbonates of alkaline earth metals decompose easily upon heating. Thanks! Why does the solubility of alkaline earth metal carbonates and sulphates in water decreases down the group? Share 0 The hydration enthalpy also decreases since the size of the cation increases. Open App Continue with Mobile Browser. Be the first to write the explanation for this question by commenting below. The sulphate of alkaline earth metals is less soluble. Order of solubility of sulphate of Alkaline earth metals BeSO 4 > MgSO 4 > CaSO 4 > SrSO 4 > BaSO 4 The greater hydration enthalpies of Be 2+ and Mg 2+ ions dominate over their lattice enthalpies and therefore their sulphates are highly soluble. The correct option is A. I know that, solubility of alkaline earth metal hydroxides increases down the group and solubility of alkaline earth metal sulfates decreases down the group. NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. Because of their higher positive charge (+2) and smaller ionic radii, the alkaline earth metals have a much greater tendency to form complexes with Lewis bases than do the alkali metals. soluble: most insol: Pb, Ba, Ca. The sulphates becomes less soluble as you fo down the group i.eMg> Ca>Sr> BaThe magnitude of the lattice energy remains almost constant as the size of the sulphate ion is so big that small increase in the size of the cation from Be to Ba does not make any difference.
