Sixth Edition 12.51

How would we be able to determine which acid is the strongest? Would we have to use periodic trends for this?

For example, between HCl and HF, which would be the stronger acid and why?

Typically the more likely it would lose an H+ ion, the stronger the acid. Therefore, the bigger the atom radius is a much stronger acid. In your example, HCl would be a stronger acid than HF since Cl is such a larger atom. You can also determine through electronegativity; F is the most electronegative ion - it would hold onto the Hydrogen much stronger. Therefore it is weaker than the HCl acid.
