Beer Lambert Law Lab Purpose: The purpose of this lab is to prove the Beer Lambert Law experimentally. The various solutions used for this experiment are tap water mixed with food colouring‚ Introduction: The Beer Lambert Law shows the relation between absorbance of light of an object‚ the molar absorptivity‚ the concentration of the substance‚ and the distance the light travels. The Beer Lambert Law states that there is a linear relationship between the concentration of a solution and the

Becca DeHaven ChemC-125 Avogadro’s Law Experiment Report Introduction: The following experiment’s purpose was to confirm Avogadro’s Law and experimentally determine the Universal Gas Constant “R”. Amedeo Avogadro hypothesized that all gases of equal volume‚ temperature and pressure would contain equal amounts of moles. This idea that volume is directly proportional to moles sprung from other similar hypotheses. Robert Boyle found that pressure and volume are inversely proportional‚ meaning as pressure

Project: Practical Investigation Aslam Khan‚ Keenan Wong and Jinhyuk Yeh 2013 Aim: To verify Snell’s Law and find the relationship between angle of incidence and the angle of refraction‚ for monochromatic light passing from air into Perspex. Hypothesis: As the angle of incidence increases so will the angle of refraction (directly proportional). Apparatus: * Laser (Monochromatic light) * Rectangular Perspex * Ruler * Pencil * Paper * Protractor * Calculator

HOOKE’S LAW EXPERIMENT Aim: The aim of this experiment is to determine the force constant (k) of the particular spring used. Introduction Hooke’s Law: Hooke’s Law is a law that shows the relationship between the forces applied to a spring and change in its length (extension). The relation is best explained by the equation: F= -k Δx F: Is force applied to the spring this can be either the strain or stress that acts upon the spring. k: Is the spring constant and details how hard

Boyle’s Law Experiment Aim To show that Pressure is proportional to the inverse to volume Method A gas syringe was attached to a pressure sensor. The pressure sensor was calibrated‚ assuming the atmospheric pressure at the time of the experiment was 100kPa. Differing volumes of gas were created in the gas syringe and they were recorded as were the corresponding values of pressure at that particular volume. The volume was varied between 20cm3 and 75cm3. Results A set of readings was obtained

LS1120 Practical 3 ABSORPTION SPECTRA AND THE BEER-LAMBERT LAW The purpose of this practical was to measure the amount of a chemical substance present in a sample. Primarily‚ the aim of Experiment 1 was to measure the absorption spectrum of a particular coloured substance (in this case Bromophenol Blue and Methyl Orange) at varying wavelengths of light. For Experiment 2‚ the process of the experiment focuses on the substance and records its absorption levels at different concentrations. The
