Question

Why does acidic character of oxides decreases down the group?

Answer 1

It became oxygen when acidic character of oxide decrease down the group

Answer 2

The non metallic character decreases down to the group. And we know that oxides of non metal are acidic in Gernal. hence acidic character of oxides down d group . Down the group the size of element increases ,electronegativity decreases, metallic character increase and acidic character decreases
