Which is more soluble in water BeO or MgO?
MgO because it is a more polar molecule than BeO. Since polar molecules dissolve polar molecules, and water is polar, the more polar molecule will have a higher solubility.

Is CaO stronger than MgO?
MgO and CaO, both have the same anion that is the oxide ion (O2-). Thus, because the lattice energy is more in MgO than in CaO, the melting point of MgO is higher than CaO. …
Why BeO and MgO are insoluble in water?
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. On the other hand, sulphate ion is a large anion. Thus, the lattice energy of BeSO4 is not very high and so it is soluble in water.
Why is CaO soluble in water?
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature….Calcium oxide.

Why is MgO soluble?
Magnesium oxide is by no means soluble in water. MgO is an ionic compound whose crystal structure is made up of Mg²⁺ cations and O²¯ anions. The thing is, such ions are so tightly held together that water by itself cannot overcome like it does with other crystalline compounds such as salts.
Why does CaO have a higher melting point than CaS?
According to Coulombs Law these forces of attraction (lattice energy) increase as the distance between ionic centres decrease and as the charges on the ions increase. This means that CaS must absorb more energy to overcome these forces of attraction, and thus, it has a higher melting temperature.
Why BeO is insoluble in water while Cao is water soluble?
Why is Cao more alkaline than MgO?
As with MgO, CaO reacts with water to form Ca (OH) 2, which is more soluble in water than Mg (OH) 2. You would therefore expect the resulting Ca (OH) 2 solution to be more alkaline than the supernatant liquid above the solid Mg (OH) 2, due to a higher concentration of OH – present.
Is Cao soluble or insoluble in water?
CaO reacts with water to form Calcium hydroxide which is only slightly soluble while MgO is clearly insoluble. Something less than 0.1g/100 mL is considered insoluble. Here are some values from Wikipedia:
