Acid Strength
Why is HF a stronger acid then HCl? I thought acid strength in this sense was determined by the electronegativity of the atom bonded to the H+ ion. Cl is more electronegative then F but on the homework it said that HF was stronger than HCl.
Re: Acid Strength
I think you might be mistaken, HCl is a stronger acid than HF.
There are 7 common strong acids and HCl is on that list, HF is not.

Re: Acid Strength
Yeah so HCl should be more acidic because it has a larger radius, therefore increasing the bond length between Cl and the H ion. This decreases the energy that it has, which makes it more stable. The more stable, the more acidic.

I wonder the same thing, but I've heard one should focus on the conjugate base. The more stable base has the stronger acid.

Re: Acid Strength
In addition, to find which compound has more basic strength, basicity, would you also have to compare conjugate acids? *That is, discovering the conjugate acid of the basic compound, ranking those on acidity, and then reversing the order ranked to find the most/least basic?
