Abstract: Objective: The objective of the work is to develop a simple precise, rapid accurate, sensitive and comparative electrochemical titrimetric method for quantitative determination of aspirin in pharmaceutical dosage form.Material and methods: The titration was carried out using standardized 0.1 M sodium hydroxide against formulated aspirin sample and all the results were statistically validated.Here Potentiometric and Conductometric titration method were used.The proposed potentiometric method was found to be precise with % RSD <1 (n = 5) as Results and Discussion: the method showed strict linearity (r > 0.99) in between 100-200 mg of drug substance weight.The percentage 2 recovery of aspirin in the optimized method was found to be lies in between 97 % to 101 %.The proposed conductometric method was found to be precise with % RSD >1 (n = 6).The method showed strict linearity (r > 0.99) 2 between 100-200 mg of drug substance weight.The percentage recovery of aspirin in the optimized method was almost 100% to the corresponding 100 and 300 mg of the drug.Potentiometric method was seems to have more Conclusion: effective one rather than the conductometric method one as aspirin can be assayed electrochemically with in concentration range with this validated method that was optimized without the effect of excipients.
