When a substance with the formula XBr₃ reacts with water, HBr and another acid, H₃XO₃, are produced. H₃XO₃ also contains three acidic hydrogens that react with KOH. After titrating a solution made up of 3.67 g of XBr₃ and 75.0 mL of water, it was discovered that 87.3 mL of 0.132 M KOH were needed to completely neutralize the acid. For the reaction of XBr₃ with water, write a balanced equation.
