At 25 °C, 1.00 L of Solution B consists of 40.4 g of sodium acetylsalicylate (NaC H704) dissolved in water. Calculate the pH of Solution B. you 2021736 = 0,20
Calculate the pH of a 0.0164 M aqueous solution of acetylsalicylic acid (aspirin) (HC9H7O4, Ka = 3.0×10-4). pH = Submit Answer
The pKa of aspirin (a.k.a. acetylsalicylic acid) is 3.40. Use the Henderson-Hasselbach equation to calculate the ratio of acetylsalicylate (i.e., the conjugate base of aspirin) to aspirin in the stomach at pH = 1.75.

a) The active ingredient in Aspirin™ is acetylsalicylic acid, HC9H7O4 (Ka = 2.75 x 10–5). To treat your headache after writing exams, you take two tablets dissolved in 250 mL of water. If each tablet contains 0.32 g acetylsalicylic acid, find the pH of the solution. Proper pH significant digit is required for full marks. b)Hydrazine, N2H4, is a base in aqueous solution. A 0.20 mol/L solution of hydrazine in water has pH = 10.77. What is Kbfor hydrazine? Express...
Common aspirin is acetylsalicylic acid, which has the structure shown below and a pKa of 3.5 Calculate the pH of a solution in which one normal adult dose of aspirin (660 mg ) is dissolved in 7.0 ounces of water.
Aspirin (acetylsalicylic acid, C9H8O4) is a weak monoprotic acid. To determine its acid-dissociation constant, a student dissolved 2.00 g of aspirin in 0.600 L of water and measured the pH. What was the Ka value calculated by the student if the pH of the solution was 2.62?
