Ka represents the acid dissociation constant and it measures the strength of weak acids.
• The higher the Ka the stronger the acid and the greater the concentration of H+
• The lower the Ka, the weaker the acid and the lesser the concentration of H+
Given the following acids and Ka values:
HCN = 4.93 x 10-10
HF = 3.53 x 10-4
HOAc = 1.76 x 10-5
Which acid is the strongest?
D. All are equally strong
