Interpretation Introduction

Interpretation:

The reason for obtaining a negative concentration while analysing an unknown analyte has to be given.

Concept Introduction:

Linear Calibration Curve:

The equation of linear calibration line is:

y(±sy)=[m(±um)]x+[b(±ub)]

Where,

y is the corrected absorbance.

corrected absorbance = observed absorbance - blank absorbance
