Well, the ionization constant is simply a ratio from a mathematical perspective. And what the Ka is, it's the amount of product formed over the amount of reactants left over. So if this number is very large, then that means a lot of product was formed and very little reactants left over. So what does that tell us about the Ha? Well, if this reaction is favored this way, if a lot of product is formed and very little reactor is left over, that means this acid is very good at giving off that age. So it must be a very good acid by definition of an acid.
