A chemistry graduate student is given 450. mL of a 1.80M 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 HC1O, solution to turn it into a buffer with pH = 1.92? 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.
