WebpKa is a value that indicates how weak or powerful an acid is in simple terms. The pKa of a strong acid is less than zero. pKa is the negative log base ten of the Ka value, to be precise (acid dissociation constant). It determines an acid’s strength, or how tightly a proton is held by a Bronsted acid. The lower the pKa value, the more ...
