Calculate the pH of a solution made by combining 40.0 ml of a 0.14 molar HBrO and 5.0 ml of 0.56 molar NaOH

  • Chem -

    40.0 mL x 0.14 M HBrO = 5.60 millimols
    5.0 mL x 0.56 M NaOH = 2.8 mmols.

    .........HBrO + NaOH ==> NaBrO + H2O
    I........5.60
    add.............2.80..............
    C.......-2.80..-2.80.....+2.80
    E........2.80....0........2.80

    Use the Henderson-Hasselbalch equation with the E line above to solve for pH
