Based on your question where there is a concentration of 1 M, the weak acid HN02 is 2% ionized nad the PH of the solution is 1.2. The possibilities that could happen to KNO2 (s) if it will dissolved into the solution is that w hen more nitrite is added to the solution, the reaction will shift towards the reactants because of La Châtelier's principle. In doing this, the solution will decrease in hydronium concentration and therefore the pH will increase by some amount.
