We’re being asked to determine which among the given aqueous solutions does the weak acid exhibit the highest percentage ionization.
Recall that the percent ionization is given by:
In which of the following aqueous solutions does the weak acid exhibit the highest percentage ionization?
a. 0.01 M HF (Ka = 6.8 x 10-4)
b. 0.01 M HNO2 (Ka = 4.5 x 10-4)
c .0.01 M HC2H3O2 (Ka = 1.8 x 10-5)
d. 0.01 M HClO (Ka = 3.0 x 10-8)
e. These will all exhibit the same percentage ionization.
