Here is a question which was given to me:

> Which of the following will give strength of acid?<br>A) pH<br>B) Normality<br>C) Degree of Dissociation<br>D) Dissociation Constant

And the answer was given as: $C$ and $D$

Now what I fail to understand is that, if pH is not considered as a metric to assess the strength of an acid because it depends on dilution (even strong acids can have high pH) then why is Degree of Dissociation a reliable metric for the same? Doesn't degree to dissociation depend on dilution aswell !?
