Why BeO is almost insoluble but BeSO4 is soluble in water?
BeO is almost insoluble in water due to high lattice energy. BeSO4 is soluble in water due to high hydration energy of Be2+ ion. The high hydration energy of Be2+ in BeSO4 overcomes the lattice energy factor and therefore BeSO4 is soluble in water.
Why BeO is insoluble but BaO is soluble?
Also due to the small size of ${ Be }^{ 2+ }$ ion it has high polarising power, so BeO has significant covalent nature (Fajan’s rules) and therefore it is insoluble in water. Whereas in BaO, the hydration enthalpy is able to overcome the lattice enthalpy and hence it dissolves in water.
Which is more soluble BeO or BeSO4?
BeO is almost insoluble but BeSO4 is soluble in water.
How would you explain I BeO is insoluble but BeSO4 is soluble in water II sodium is kept in paraffin oil III LiI is more soluble than Ki in ethanol?
Answer Expert Verified (i) Lattice energy of BeO is greater than its hydration energy so, it is insoluble in water while in case of BeSO4 , hydration energy is greater than lattice energy, so, it is readily soluble in water. that’s why LiI is more soluble than KI in ethanol(covalent compound).
How would you explain the following I BeO is almost insoluble but BeSO4 is soluble in water II Ba OH 2 is soluble in water while BaSO4 is almost insoluble?
Lattice energy of BeO is comparatively higher than the hydration energy. Therefore, it is almost insoluble in water. Both BaO and BaSO4 are ionic compounds but the hydration energy of BaO is higher than the lattice energy, therefore it is soluble in water.
Is BeSO4 a solid?
Beryllium sulfate normally encountered as the tetrahydrate, [Be(H2O)4]SO4 is a white crystalline solid. Beryllium sulfate may be prepared by treating an aqueous solution of many beryllium salts with sulfuric acid, followed by evaporation of the solution and crystallization.
Why is BeO soluble in water?
BeO is almost insoluble in water and BeSO4 is soluble in water because Be2+ is a small cation with a high polarising power and O2– is a small anion. Therefore, the lattice energy released during their formation is also very high. Thus, the lattice energy of BeSO4 is not very high and so it is soluble in water.
Which is more soluble BeO or BaO?
The lattice energy of BeO is higher than BaO due to small size of Be2+ ion.
Is BeSO4 aqueous?
Beryllium sulfate is an important salt of beryllium used as an intermediate of high purity for calcination to beryllium oxide powder for ceramic applications. A saturated aqueous solution of beryllium sulfate contains 30.5\% BeSO4 by weight at 30 °C and 65.2\% at 111 °C.
How would you explain the following I BeO is almost insoluble but BeSO4 is soluble in water II BA OH 2 is soluble in water while BaSO4 is almost insoluble?
How would you explain Ba is soluble but BaSO4 is insoluble in water?
The lattice enthalpy of BaO is less than its hydration enthalpy, because of the large size of Ba ions and smaller size of the oxide ion. Therefore BaO is soluble in water. Therefore BaSO4 is insoluble in water.
