How can you tell how strong a certain oxide acid is?

Question

Given a list of acids containing oxygen, how do you determine the order of their strength?

Answer 1

The definition of an acid's strength comes from the Ka (acid dissociation constant) which shows how easily the acid dissociates in water. Therefore having a list of oxide acids you need their Ka. Of course an estimate can be made considering the electronegativity of the products of the dissosiation.
