Proton transfer fundamentals

Proton transfer reactions As you should recall from your earlier introduction to acids and bases the +1 electric charge of the tiny proton (a bare hydrogen nucleus) is contained in such a miniscule volume of space that the resulting charge density is far too large to enable its independent existence in solution it will always attach to and essentially bury itself in the non-bonding

Diprotic and Triprotic Acids and Bases

Diprotic Acids The acid equilibrium problems discussed so far have focused on a family of compounds known as monoprotic acids Each of these acids has a single H + ion or proton it can donate when it acts as a Brnsted acid Hydrochloric acid (HCl) acetic acid (CH 3 CO 2 H or HOAc) nitric acid (HNO 3) and benzoic acid (C 6 H 5 CO 2 H) are all monoprotic acids

Why HF is a weaker acid than HCl?

Because of strong affinity of fluorine for hydrogen so it strongly holds hydrogen and don't loose it very easily As in HCl due to lesser H-Cl bond dissociation enthalpy as compared to HF HCl is stronger acid than HF This is the basic concept for the reason why HF is a weaker acid than HCl
