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 HNO2 is as follows:
HX(aq) + H2O(l) ⇌ H3O+(aq) + X–(aq)
An acid HX is 25% dissociated in water. If the equilibrium concentration of HX is 0.30 M, calculate the Ka value for HX.
