Consider a solution formed by mixing
50.0 mL of 0.100 M H2SO4,
30.0 mL of 0.1000 M HOCl,
25.0 mL of 0.200 M NaOH,
25.0 mL 0.100 M Ba(OH)2, and
10.0 mL of 0.150 M KOH.
Calculte the pH of this solution.
Ka (HOCl) = 3.5 x 10-8
What is the pH?
first to calculate moles of each.
then to calculate Molarity of each in total volume.
then to calculate OH- concentration
the H+ concentration from strong acid.
both are completely neutralize.
then using ICE table to find pH of weak acid and remaining OH-.
