The dissociation of HNO2 is as follows:
HA(aq) + H2O(l) ⇌ H3O+(aq) + A–(aq)
From this, we can construct an ICE table. Remember that liquids are ignored in the ICE table and Ka expression.
The Ka expression for HA is:
A 0.50 M solution of an acid HA has pH = 2.24. What is the value of Ka for the acid?
