Question

Which is more soluble among the following?
A. CaO
B. MgO
C. BaO
D. BeO

Answer 1

Answer:

In metals moving down the group metallic character increases, so basic nature increases hence most acidic will be BeO as Be is least metallic in group 2 elements.

BeO is most acidic in nature as the acidity of oxides decreases with increases in the electropositive character of the central atom.
