Extract of sample "Factors that Affect the Intensity of Color"

It was noted that transmittance reduced with an increase in the concentration of the solutions. Therefore, an inverse relationship existed between transmittance and concentration. The green and red solutions provided linear relationships between concentration and transmittance. The equation % T=1/%Concentration was established where % transmission increased with a decrease in concentration.

The above equation meant that plotting %T on the y-axis and 1/% concentration on the x-axis gave a straight line that passed through the origin (y-intercept as zero). However, it was not possible to obtain a precise linear relationship between transmittance and concentration for the blue and blue-green solutions. Overall, the aim of the experiment was achieved because a relationship between transmittance and concentration was obtained. However, the setup could be improved further by increasing the percentage concentrations, for example, from 0% to 5% to 10%, and so on.

Additionally, the solutions that did not yield good linear results (blue and blue-green) could be diluted further to enable the establishment of a linear relationship between transmittance and concentration. It was concluded that spectrophotometry was a reliable technique in the determination of the concentrations of colored solutions.
