Answer in scientific notation with appropriate sigfigs considered. A buffer solution is prepared by combining (1.41x10^1) mL of (2.000x10^-1) molar acetic acid with (1.8x10^1) mL of (2.40x10^-1) molar sodium acetate. What is the concentration of weak base in this solution?
Hello, I have an answer with this but I don't know if I'm correct... My answer is 0.508 g, can you calculate if my answer is correct? calculate the given problem using Hasselbach Equation. acetylsalicylic acid is absorbed from the stomach in the free (nonionized) acid form. If a patient takes an antacid that adjusts the pH of the stomach contents to 2.95 and then takes two 5-grain aspirin tablets (total 0.65 g), how many grams of aspirin are available for immediate absorption from the stomach, assuming immediate dissolution? Also assume that aspirin does not change the pH of the stomach contents. The pKa of aspirin is 3.50, and its formula weight is 180.2.

You are asked to prepare a buffer solution with a pH of 3.50. The following solutions, all 0.100 M, are available to you: HCOOH, CH3COOH, H3PO4 , NaCHOO, NaCH3COO, and NaH2PO4. What ratio of [conjugate base]/[acid] would yield the best result for the required buffer solution created in the question above? ENTER YOUR ANSWER AS ONE NUMBER ROUNDED TO TWO DECIMAL PLACES.
What is the pH when 100 mL of 2M NaOH is added to 100 mL of 1M acetic acid and H2O is added to make a final volume of 0.5L? (pK acetic acid= 4.76) The answer is 13.3 pH This was a practice problem from class. I was told that you can't use the Henderson–Hasselbalch equation for this problem because the NaOH is in excess. Could you explain step by step to get the answer?
