A?33.0?mL sample of a?0.406?M aqueous?hypochlorous acid?solution is titrated with a?0.387?M aqueous?barium hydroxide?solution. What is the pH after?6.54?mL of base have been added? pH =??7.24 Feedback: Please note that while the results of the intermediate calculations below are displayed rounded to 3 significant digits, the actual calculations are done internally without rounding. When the strong base,?Ba(OH)2, is added, the weak acid reacts to neutralize the OH-.The balanced equation is:? 2?HClO?+?Ba(OH)2??Ba(ClO)2?+?2?H2O The initial number of moles of the weak acid?HClO?is given by?0.406?M??3.30E-2?L =?1.34E-2?mol Similarly, the number of moles of?Ba(OH)2?added is given by?0.387?M??6.54E-3?L =?2.53E-3?mol
