Phosphorous acid, H3PO3(aq), is a diprotic oxyacid that is animportant compound in industry and agriculture.
Calculate the pH for each of the following points in thetitration of 50.0 mL of a 1.5 M H3PO3(aq) with 1.5 M KOH(aq).
pKa1= 1.30
pKa2= 6.70
(a) before addition of any KOH =_____number
(b) after addition of 25.0 mL of KOH = ______number
(c) after addition of 50.0 mL of KOH = ______number
(d) after addition of 75.0 mL of KOH =_______number
(e) after addition of 100.0 mL of KOH=______number
please explain how you got each! thanks so much
