millimoles of HCl = 15*0.6 = 9 KOH = 25*0.35 = 8.75 so millimoles of H+ ions
(in form of HCl that remain un-neutralized) = 9-8.75 = 0.25 so [H+] = 0.25 millimoles or 2.5e-
4M pH = -log(2.5e-4) = 3.6
Solution
millimoles of HCl = 15*0.6 = 9 KOH = 25*0.35 = 8.75 so millimoles of H+ ions
(in form of HCl that remain un-neutralized) = 9-8.75 = 0.25 so [H+] = 0.25 millimoles or 2.5e-
4M pH = -log(2.5e-4) = 3.6
