WebIn simple terms, pKa is a number that shows how weak or strong an acid is. A strong acid will have a pKa of less than zero. More precisely – pKa is the negative log base ten of the Ka value (acid dissociation constant). It measures the strength of an acid — how tightly a proton is held by a Bronsted acid. WebCH 3CH 2COOH will have highest value of pKa. Others have electronegative halogen atom on alpha or beta carbon atom which increases the acidity and decreases the pKa value.
