After completing the procedure of the laboratory experiment in its entirety, it was 
concluded that phosphate concentration was in direct proportion to absorbance in each of 
the three cola samples. The trend line equation, “y = 0.107x + 0.549” summarizes the 
correlation between absorbance and concentration in phosphate solutions. When applied 
to this particular experiment, the equation yields a concentration of .61 M for Coke. This 
was the highest concentration of the three samples, foll...
