3) In another experiment, a European brand low dose aspirin tablet was placed in a 500-ml volumetric flask and dissolved in 20 mL of 1.0M NaOH solution, the flask was then filled to the mark ( 500 mL) with deionized water. Using a pipette 50.0 mL of this solution was added into a 100-mL volumetric flask and diluted to the mark with FeCl3 solution. The absorbance recorded for the European aspirin tablet was 0.185.
