The hydration enthalpies of BeSO 4 and MgSO 4 are quite high because of small size of Be 2+ and Mg 2+ ions. On the other hand in BaSO4 the size of Ba ions and sulphate ions are very large and therefore the lattice enthalpy is much larger than the hydration enthalpy. As an amorphous solid, beryllium oxide is white.Its high melting point leads to its use as a refractory material. Beryllium Sulphate is the least soluble of the group 2 sulphates and does not react with water therefore is insoluble. 3.1.2.5 UO 2 –BeO. It is a metal sulfate compound which is used in water treatment plants. Barium sulphate, or BaSO4, is insoluble in water. Beryllium Sulfate is a white colored, crystalline, inorganic compound that emits toxic fumes of beryllium oxides and sulfur oxides upon heating. So water cannot break them . BeO is almost insoluble but BeSo4 is soluble in water explain. The mhydrogen atom is replaced by a metal compound. Beo is insoluble but beso4 is soluble in water. Beo is soluble but beso4 is in soluble in water Get the answers you need, now! When BeO is dissolved in water, the hydration energy of its ions is not sufficient to overcome the high lattice energy. Bigger radius bigger ionic nature.

... Why BeSO4 is water soluble but BaSO4 ... Beryllium Sulphate is the least soluble of the group 2 sulphates and does not react with water therefore is insoluble. Therefore, BeO is insoluble in water. On the other hand, sulphate ion is a large anion. Beryllium oxide has a high melting point (~2500°C) and high thermal conductivity (230–330 Wm −1 K −1), good chemical compatibility with UO 2 below 2160°C, low neutron capture cross section, good neutron moderation and high resistance to water steam. Beryllium oxide (BeO), also known as beryllia, is an inorganic compound with the formula BeO. Barium sulphate is an ionic compound with a low melting point. How would you explain :- i ) BeO is insoluble but BeSO4 is soluble in ... therefore the lattice energy of BeO is larger than the hydration energy. When BeO is dissolved in water, the hydration energy of its ions is not sufficient to overcome the high lattice energy. Therefore, BeO is insoluble in water. Hence, Lattice energy of BeO is higher than BaO due to small size of Be 2 + and its covalent nature. But BaSo4 has more ionic nature than Na2So4 .Because radius of the Ba2+ is bigger than Na+ . SIlver Ion Test from USP (drug testing book) → Treat unknown solution with NaCl, precipitation of AgCl, which does NOT dissolve in nitric acid. This is because the greater hydration enthalpies of Be 2+ and Mg 2+ ions overcome the lattice enthalpy factor and therefore their sulphates are soluble in water. The solubility of the alkaline earth metal sulphates decrease down the group. This colourless solid is a notable electrical insulator with a higher thermal conductivity than any other non-metal except diamond, and exceeds that of most metals. Therefore BaO is soluble in water. Beo is insoluble in water because of its high lattice enthalpy.It is also covalent in nature and therefore , insoluble in water.On the other hand , BeSO4 is ionic.Its hydration enthalpy is much more than its lattice enthalpy and hence it is soluble in water. Marco Cologna, in Reference Module in Materials Science and Materials Engineering, 2020. BeO is almost insoluble but BeSO4 IN soluble in water. BeSO4 is moderatetly water soluable.

The mhydrogen atom is replaced by a metal compound.
