What is the concentration of unknown sample in a spectrophotometer?
Thus it can be concluded that the estimated concentration of unknown sample could be around 0.045mg/ml. In the initial phase of the lab, it demonstrated the use of a spectrophotometer to analyze the optimal wavelength of absorbance for different solutes.
What should be included in a spectrophotometer lab report?
This report presents the procedures for the experiment, the experiment's results, and an analysis of those results. In this experiment, cuvettes containing a reagent blank is inserted into the spectophotometer with the meter adjusted to read zero absorbance.
How is absorption of light used in spectroscopy?
For this practical the method used is visible spectroscopy via the use of a spectrophotometer. This equipment measures the amount of light absorbed by passing a beam of light through the sample and the amount of light is measured by a detector. This produces an absorbance value which can be used to calculate concentrations.
How is absorption related to Beer-Lambert's law?
This report discusses an experiment to study the relationship of absorbance and concentration, the interaction of electromagnetic radiant energy (ERE) and matter which is an important aspect of the Beer-Lambert's Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound.
