The Kа оf lаctic аcid, CH3CH(OH)CO2H, a weak mоnоprotic acid found in the blood after strenuous exercise, is 1.36 × 10-4. Build a RICE table or write the correct expression for Ka and calculate the pH of 0.222 M solution of lactic acid. Upload your table and calculations to the Exam Calculations assignment after you submitted your exam. Answer: 3 points; Calculations and RICE Table - 3 points.
