A chemistry graduate student is given 450. mL of a 0.70M chlorous acid (HCIO,) solution. Chlorous acid is a weak acid with K= 1.1 × 10 . What mass of KCIO, should the student dissolve in the HCIO, solution to turn it into a buffer with pH = 2.24? You may assume that the volume of the solution doesn't change when the KCIO, is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.

Question
A chemistry graduate student is given 450. mL of a 0.70 M chlorous acid (HCIO2) solution. Chlorous acid is a weak acid with K=1.1 x 10^-2 . What mass of KClO, should the student dissolve in the HCIO, solution to turn it into a buffer with pH = 2.24? You may assume that the volume of the solution doesn't change when the KCIO, is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.
