Question

Acids donate protons to water according to the general equation:
HA(aq) + H2O(l) H3O+(aq) + A-(aq)
Consider the following acids and their equilibrium constants for reaction with water at 25C. If all the acids have the same initial concentration, which is the strongest acid (i.e. which donates the most protons to water)?
A) HBrO, Kc = 2.0 10-9
B) HNO2, Kc = 4.5 10-4
C) HF, Kc = 3.5 10-4
D) HIO3, Kc = 1.7 10-1
