During analysis, it is important to first determine the absorbance spectrum. This shows how the wavelength affects the absorbance of photons. The spectrum itself is a plot of the wavelength against the absorbance, and is characterized by the maximum wavelength at which there is the greatest absorbance. This wavelength characterizes molecules in the compound and provides information about the electronic structure of the sample to be analyzed. The photon absorbance of the molecules of the sample are measured and used for the preparation of the calibration curve, which shows how absorbance relates to the concentration of the molecules in the solution.
In the course of this experiment the intensity of light photons for the sample was measured, and absorbance and transmittance were duly calculated. The extent to which photons are absorbed depends heavily on the wavelength of light. As such, spectrometry is performed with the use of monochromatic light, which is light in which all photons possess the same amount

Consequently, a destabilized protein level in the body, through inappropriate nutrition or through effects of diseases adversely affects body processes. The study of protein concentration in the body, as well as in substances is therefore fundamental to nutritionists and health care professionals.
There is sharp drop in the electrode potential near the equivalence point. Two equivalence points were observed in these experiments – one corresponding to KI and another corresponding to KCl. The equivalence point was determined using
A Redox reaction is one in which there is transfer of electrons from one species to the other (Web, Undated). In this experiment, an attempt has been made to determine the concentration of an unknown solution of Potassium permanganate (Chemical Formula: KMnO4)
It seeks to classify and research on chemicals. A lab instrument that is used to carry out this research is the Fourier transform infrared spectrometer. The Fourier transform Infrared spectrometer gives an electromagnetic spectrum that is
The main objective of this experiment is to standardize i.e. find the exact concentration of Potassium Permanganate Solution. The concentration is expressed in Moles per litre (M). A 0.02moldm-3 is prepared and its exact molarity determined by titration.
that matter can go through any physical or chemical reaction, but the total mass of the reactants and the products will remain equal (Rogers et al., wisc.edu).
The experiment aims to illustrate the Law of Conservation of Mass by reacting zinc metal and iodine to synthesize zinc
The chemical structures of molecules can thus be drawn.
The process is done by creating charged particles from molecules. The sample which may be solid, liquid or gas is charged by bombarding it with electrons. This results into the molecule sample disintegrating as
Soft ionization converts the macromolecule under investigation in the presence of a polar volatile solvent into tiny droplets, which are further desolvated into smaller droplets hence forming molecules that are
The peptides are mostly associated with the degradation of proteins especially because of their association with lysosomes. The present study involved the synthesis of cathepsin molecule. The experiment aimed to obtain Z-cbz-Phe-Arg(OH) hence used
