Estimate the pKa of the acid has to be calculated.

Concept introduction:

UV/vis spectroscopy: It is deal with information about various compounds that have conjugated double, the UV light and visible light have jest the right energy to cause an electronic transition in a molecule that is to promote an electron from one molecular orbital to another higher energy.

pH: The pKa of a compound was determined using the UV/Vis spectroscopy if either the acidic from or the basic from of the compound absorbs UV or visible light.

Henderson-Hesselbalch equation: The acid lose a proton in an aqueous solution depends on the both the pKa of the acid and the pH of the solution, the relationship between the two is given by equation.

pKa= pH+ log [HA][A−]

The concentration of a dilute aspirin solution is 0.000530 M 0.000530 M . Standard solutions of this compound were used to prepare a Beer's law plot which gives a slope of 1550.1 M −1 1550.1 M − 1 . What is the expected absorbance value for the aspirin solution?

1.) Beer's Law can be used to find the concentration of a solution by measuring its absorbance. The law is given by ?=???A=ϵbC Where A is the absorbance, ?ϵ is the molar absorptivity, b is the pathlength of the light (the width of the sample cell), and C is the concentration of the solution. A student is analyzing a solution of a metal, and finds that the absorbance of the solution is 0.532.
