How does hydrolysis of 0.02M of aspirin in buffered solution (pH = 7) changes at increasing temperature (298, 308, 318, 328, 338K) measured by a colorimeter?

 

Introduction

A daily low-dose aspirin helps to prevent heart attacks and strokes in people at high risk of them (NHS). It is one of the most extensive drugs that many people take to relieve fever or pain. However, the time required for body to absorb dissolved aspirin is extremely critical. In this sense, methods such as dissolving aspirin beforehand in water to drink or in an IV solution to inject have actively used as alternatives (Safemedicationus). Thus, the primary objective of this investigation is to determine ‘how does changing temperature of pure water impact the reaction rate in aspirin hydrolysis?’

 

Scientific Background

Acetylsalicylic acid (ASA) is a hydrolytically sensitive drugs, water acts as a reactant and increases the drug degradation rate directly by participating in a bimolecular reaction. (Mahato) Hydrolysis of aspirin is a reaction of acetylsalicylic acid breaks down into salicylic acid and acetic acid by using water…
