A new potential heart medicine, code-named X-281, is being tested by a pharmaceutical company. Pharma-pill. As a research technician at Pharma-pill, you are told that X-281 is a monoprotic weak acid, but because of security concerns, the actual chemical formula must remain top secret. The company is interested in the drug's K, value because only the dissociated form of the chemical is active in preventing cholesterol buildup in arteries. To find the pK, of X-281, you prepare a 0.083 M test solution of X-281 at 25.0 °C. The pH of the solution is determined to be 2.70. What is the pKa of X-281? Express your answer numerically. > View Available Hint(s) redo pKa = Submit Part B Complete previous part(s) Provide Feedback Next > P Pearson
