A student is conducting a titration lab as part of their Grade 12 Chemistry course. The procedure asks them to titrate 35.00 mL of a 0.0.64 mol/L hydrobromous acid, HBrO(aq), a weak acid, with 0.150 mol/L of strong potassium hydroxide solution, KOH(aq). They observe the equivalence point is reached when 15.00 mL of the base has been added. The student has already done some calculations and found that 0.00224 mol of acid and base were used to make 0.00224 mol of the basic salt. What should the student calculate as the pH at the equivalence point, given Kb = 3.6 x 10^-6? Include any tables, formulas, and balanced reactions used. The acid-base equation has been provided. [HINT: Start by finding the concentration of salt!] *SHOW YOUR WORK! HBrO (aq) + KOH(aq) -> H₂O(l) + KBrO (aq)
