WebTwo weak acids, A and B, have pKa values of 4 and 6, respectively. Which statement is true? a) Acid A dissociates to a greater extent in water than acid B. b) For solutions of equal concentration, acid B will have a lower pH c) B is conjugate base of A d) Acid A is more likely to be a polyprotic acid than acid B WebLet's look at some Ka values for some weak acids at 25 degrees Celsius. Hydrofluoric acid has a Ka value of 6.3 times 10 to the negative fourth, and acetic acid has a Ka value of 1.8 times 10 to the negative fifth. Since both of these have Ka values less than one, they're both considered to be weak acids.
