What is the pKa of hydrofluoric acid?
pKa 3.8
It has multiple industrial and household uses (Box 15-1). The damage caused by HF is concentration dependent and largely related to the fluoride component rather than its corrosive hydrogen ion. Because HF is a relatively weak acid (pKa 3.8), it is largely nonionized and can penetrate cell membranes easily.

Which is the correct pKa value for hydrochloric acid?
As a result, recommended pKa values in water and DMSO are assigned to hydrochloric acid, hydrobromic acid, hydroiodic acid, perchloric acid and trifluoromethanesulfonic acid (triflic acid). In some cases the currently accepted pKa values were revised by more than 10 orders of magnitude
