a only HClO is present we know that HClO is a weak acid and for weak acids H sqrt Ka x C so H sqrt 29512 x 108 x 021 H 7872 x 105 now pH log H so pH log 7872 x 105 pH 4104 b now moles molarity x volume L so moles of HClO 021 x 50 x 103 105 x 103 moles of KOH 021 x 25 x 103 525 x 103 now the reaction HClO KOH KClO H20 we can see that moles of HClO reacted moles of KOH added 525 x 103 so moles of HClO left 105 x 103 525 x 103 525 x 103
