The degree of dissociation of acetic acid in a 0.1 M solution is 1.32×10−2, find out its pKa value. Take log10(1.76)=0.25
Calculate the degree of ionization of 0.05M acetic acid if its pKa value is 4.74.
How is the degree of dissociation affected when its solution also contains (a) 0.01 M (b) 0.1 M in HCl?
