We’re being asked to calculate the equilibrium constant of HClO2 if a 1.43 M solution is 8.0 % ionized.
Recall that the percent ionization is given by:
Remember that weak acids partially dissociate in water and that acids donate H+ to the base (water in this case).
The dissociation of HClO2 is as follows:
HClO2(aq) + H2O(l) ⇌ H3O+(aq) + ClO2–(aq)
At a certain temperature, the percent dissociation (ionization) of chlorous acid, HClO2, in a 1.43 M solution water is 8.0%.
Calculate the value of Ka for chlorous acid at this temperature.
