If the legal minimum acetic acid content in vinegar is 1.50M, which of the two vinegar enthusiasts- Rei, Akari, or BOTH, are allowed to sell their vinegars for business?
Rei and Akari, two vinegar enthusiasts, are each tasked to determine the acetic acid content of their respective vinegar concoctions by titration. First, a 1 M-labeled KOH solution was standardized against the KHP (MW = 204.22 g/mol) standard that is 99.4% pure. In the process, 0.540 g KHP was found to require 2.80 mL of the KOH solution to completely react up to the phenolphthalein endpoint. Then, Rei and Akari both prepared their samples by taking 10.0-mL aliquots of each vinegar and diluting them to 25.0 mL. Using the same titrant and indicator, Rei's vinegar required 18.60 mL of the standardized titrant to reach the endpoint, while Akari's vinegar required 16.50 mL of the same titrant to reach the same endpoint.
