Question

metals always gives basic soln. and non metals always gives acidic soln. why

Answer 1

Answer:

Recently I came across the fact: Metal oxides basic and non-metals' acidic or neutral.

Searching for it, partly my query is solved, as I found:

Metal oxides or O2− forms OH− after hydrolysis in the following reaction so metal oxides are basic in aqeous solutions.

O2−+2H2O⟶4OH−

I think this might happen as metal form ionic compunds and non-metals form covalent and some of them may not even react tus neutral.

I've got only a little 5% of the exact reason, therefore I wish if someone could explain the whole process/fact. I considered Arhenius concept.
