Can Pka Be Negative?

A pKa may be a small, negative number, such as -3 or -5. ... The lower the pKa of a Bronsted acid, the more easily it gives up its proton. The higher the pKa of a Bronsted acid, the more tightly the proton is held, and the less easily the proton is given up.

What does negative pKa mean?

pKa is the negative log of the acid dissociation constant or Ka value. A lower pKa value indicates a stronger acid. That is, the lower value indicates the acid more fully dissociates in water.

Can a Ka value be negative?
