What is the order of solubility of gr2 oxides(be0,mg0.....ba0)
Also give the explanation .
Since water is polar, the more polar molecule will have higher solubility. Polarity is determined by the difference in electronegativity between two atoms.
Since Mg and Ba's electronegativity is 1.2 and 0.9 respectively, and O's electronegativity is 3.5, the difference between O and Ba is larger than that between O and Mg. Therefore BaO is more soluble than MgO.
as you move down group electronegativity of metal will decrease, hence difference will increase so will polarity so will will solubilty.
Since polar molecules dissolve polar
molecules, and water is polar, the more polar
molecule will have a higher solubility.
Polarity is determined by the electronegativity
of elements in a compound. A higher
electronegativity essentially means that the
molecule holds its electrons closer to its
nucleus. And when 2 elements in a molecule
have different electro negativity's, it causes one
of the elements to hold the electrons more
closely to their nucleus. This causes the
element with the higher electronegativity to
have a slightly negative charge, and the
element with the lower electro negativity to
have a slightly positive side. This is called a
Dipole-Dipole and it causes compounds to be polar
