Answer / pratap rasam
At pKa half of the compound is in acid form and remaining
half in the base form. Also, it is nothing but the pH at
half neutralization. Smaller the value of pKa stronger the
acid and vise-versa. It is the inverse of dissociation
constant K.

Answer / nishabd
Definition of pKa :
(pK for short). The negative logarithm of the acid dissociation constant, Ka.
Just like the pH, the pKa tells you of the acid or basic properties of a substance.
pKa <2 means strong acid
pKa >2 but <7 means weak acid
pKa >7 but <10 means weak base
pKa >10 means strong base
