Weak Acid Strength
What is the best way to determine which acid is stronger if you are given two different types of weak acids? Is there a foolproof step you can use to determine it?

Re: Weak Acid Strength
The greater the electronegativity of A in A-H for binary acids, across a period, the stronger the acid. The stronger the bond between A and H in A-H down a group, the weaker the acid. For oxoacids, the greater the number of oxygen atoms bound to the central atom, the stronger the acid. Oxoacids can readily lose H+ if resulting anion is stabilized by electron withdrawing atoms which delocalize and stabilize the negative charge.
Re: Weak Acid Strength
Following periodic trends is a good way to determine this. Atoms with smaller radii will form weaker acids because the bonds are stronger.
