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.

Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.
