ABSTRACTThe experiment was conducted in order to find the relationship of a certain element(sodium) concentration to the atomic radiation emission by the excited electrons as they return totheir relaxed stage. The experiment also involved titration wherein the products were used as thestandard sodium solutions to be used as the samples for data gathering. Unknown sodiumconcentrations samples were also involved to check if atomic radiation emission can predictatomic concentration. The data management includes collection of flame intensity images to beanalyzed using R statistics. It was found out that both of the known and unknown concentrationsamples showed direct proportion of the sodium concentration to the llvll or the atomic radiationemission multiplied by certain coefficients (acquired from the R statistics). However, using theatomic radiation emission to predict the concentration values need more validation as they aremany errors that could arise such as contamination and inaccurate image processing.
Chapter 1INTRODUCTION1.1 Rationale of the ExperimentSpectroscopy experiments (involving the hydrogen atom) were done and the findingssuggested that as electrons move into higher energy levels, an electromagnetic radiation isemitted. Henceforth, previous experiments of the past concerning on the excited states of theenergy levels of certain atoms led researches to observe that spontaneous emission of radiation isconnected to the certain atom concentration.A study by Morals and Lima (2014), explored the intensity of sodium emission and itsrelationship to the sodium concentration samples by manipulation of the intensities of the RGBchannels. The intensity of sodium emission is mathematically explained by the formula:INa3p-3s=hvNa3s-3pANa3s-3pNNa3pWhereinhis the Planck’s constant, vNa3s-3pis the average probability per unit time of onesodium atom in the sodium samples making a radiative transition between the discrete energystates 3p-3s and NNa3pis the average number of sodium atoms in the 3p energy level.This laboratory experiment adopted the procedures of Morals and Lima (2014) studywhich introduced a low cost method to quantify sodium content on chemicals having unknownsodium concentrations. The experiment involved capturing sodium radiation emission photosfrom burning using available phone cameras. It also used R statistics which can provide accuratestatistical data from various platforms of data inputs. Meanwhile, the images were used as inputs
for the EBImage package (bioconductor.org) which is still a part of the R package as it can helpnormalize data especially those gathered from bioinformatics related information.1.2 Objectives of the ExperimentThe main objective of this experiment is to assess and determine the relationship of thesodium atomic radiation emission and the sodium concentration. The experiment will alsoaddress the following objectives:1.Determine the RGB radiation emissions of the standardized sample solutions ofsodium;2.Determine both the RGB radiation emissions and sodium concentrations of theunknown samples;3.Usage of R statistics for the gathered qualitative data
