The pKa of this acid is mathematically given as

pKa=4.74

What is the pka of this acid?

Question Parameter(s):

The acid dissociation constant, ka, of acetic acid is 1.8 x 10-5

Generally, the equation for the pKa  is mathematically given as

pKa=-log( Ka).

Therefore

pKa=-log10(1.8*10-5)

pKa=4.74

In conclusion, the pKa of this acid

pKa=4.74
