About this document
Acetylsalicylic Acid Content in Aspirin by Lovely Esmeralda is a document available to read on EtoBox.
The document describes an experiment to determine the percentage of acetylsalicylic acid (% ASA) in an aspirin tablet through back-titration. The experiment involved preparing 0.1M HCl and standardizing NaOH solutions, then using them to back-titrate an aspirin sample. The calculated % ASA was much lower than expected at 21.29% instead of the expected 70%. This was attributed to the actual molarities of the NaOH and HCl solutions being lower than the expected 0.1M concentrations. Due to the large difference
