Remember that weak acids partially dissociate in water and that acids donate H+ to the base (water in this case).
The dissociation of HClO is as follows:
HClO(aq) + H2O(l) ⇌ H3O+(aq) + ClO–(aq); Ka = 3.0 × 10–8
From this, we can construct an ICE table. Remember that liquids are ignored in the ICE table and Ka expression.
The Ka expression for HClO is:
The Ka of hypochlorous acid (HClO) is 3.0 x 10-8 at 25.0 °C. What is the percent ionization of hypochlorous acid in a 0.015 M aqueous solution of HClO at 25.0°C?
b. 4.5 x 10-8
c. 1.4 x 10-3
e. 2.1 x 10-5
