Ka Is dissociation constant of acid.pKa Value determines if the acid is strong or weak acid.

The value of ka=1.0×10-3,pKa=3,so the acid is weak acid.

In weak acid it is assumed that dissociation is very less with respect to initial concentration of acid at beginning.

If it is not done,then the calculation of pKa will be much complicated.
