Ph range of acetic acid
WebThe U.S. Food and Drug Administration requires vinegar to contain at least 4% acetic acid, but may range up to 8% in commonly used vinegars. Although acetic acid is responsible for the tart and pungent flavors and odors we recognize, vinegar also contains trace vitamins, mineral salts, amino acids, and polyphenolic compounds [1]. WebK4 for acetic acid is 1.7 105 at 25C. A buffer solution is made by mixing 52.1 mL of 0.122 M acetic acid with 46.1 mL of 0.182 M sodium acetate. Calculate the pH of this solution at …
