A 30.00ml sample of 0.1234 M hypobromous acid (HBrO) is titrated with a 0.2555 M KOH solution. The Ka for HBrO is 2.5*10^-9

Calculate the pH of the titration mixture at the equivalence point.

  • Chemistry - ,

    You must recognize what you have at the equivalence point. In this titration, the HBrO has been neutralized with KOH to produce the salt KBrO. The salt will be hydrolyzed. Set up an ICE chart, substitute into Kb for the salt (Kb = Kw/Ka) and solve.
