Determine the volume (in mL) of 1.470 M KOH, needed to reach the equivalence point for the titration of a solution of 166 mL of HNO2 (K, = 5.62e – 04) at a 0.820 M concentration. Calculate the pH of the solution at the equivalance point. Volume of base (mL) = number (rtol=0.01, atol=1 pH = number (rtol=0.01, atol=14-08) ?
