beo पानी में अघुलनशील है, जबकि cao घुलनशील क्यों है

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. ... When BeO is dissolved in water, the hydration energy of its ions is not sufficient to overcome the high lattice energy.

Answer 2

Answer:

Yes

Explanation:

• For comparing the solubility of any compounds first we should see the radius difference between the constituents in the compounds. If more is the radius difference then more is the solubility of the compound.          

• Then we should also consider the lattice energy and the hydration energy of the compounds.

• Be⁸⁺ is a smaller cation with a high polarising power and O⁸⁻ is a smaller anion.  When BeO is dissolved in water, the hydration energy of its ions is not sufficient to overcome the high lattice energy.
• In case of the CaO also the same criteria as that of the BeO follows but the hydration energy of the compound is sufficient to overcome the lattice energy.
