-2 A chemistry graduate student is given 100. mL of a 0.80M 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 = 1.37? You may assume that the volume of the solution doesn't change when the KC10, is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. x10
