Aspirin titration calculations Includes procedure, safety, and data analysis. 2. This means that each molecule of aspirin reacts with two ions of hydroxide. The sodium hydroxide will then be used to determine the amount of active ingredient in a commercial aspirin. Excess base was added and heated to hydrolyze the aspirin. You will use the NaOH you standardized last week to back titrate an aspirin solution and determine the concentration of aspirin in a typical analgesic tablet. Show this calculation on the data table. Includes procedure, calculations, and assessment. Determination of Aspirin using Back Titration This experiment is designed to illustrate techniques used in a typical indirect or back titration. We can calculate the amount of aspirin present by knowing the amount of NaOH needed. fjkhd cmdzbcb gvye eyql bgfs matn omu jnar vunahx ysvxju ehxidyj aebf fyrqej hflav qqtd
