I. 	 Cola Lab – determination of the Acid in a solution. 

II.	Purpose – The purpose of the cola lab is to analyze the phosphoric acid  content of a cola drink using two methods of data collection and concentration determination.  

III.	Procedure – A sample of a cola drink containing cola should have been used in this experiment, however, I used a ‘sprite’ type to have a comparison, as this is what I determined to be a cola, having misinterpreted the generic term.  The run of the experiment was such, that a titration was set up using standard laboratory equipment, and an electronic pH meter attached to the computer as a  data collection device for input into a table and or graph.   For the second step of the analysis.  A sample from another student of the actual phosphate cola was used for the second step, also the spectral analysis in this lab.  I do however, wish that I had used my ‘sprite’ sample and to have collected the data with this sample.    

IV.  Data and Interpretation.   I am unable to open the Logger-Pro data which I collected with the computer from the library, and have no available data and or information from which I can obtain results.  

VI.  Conclusion:  From memory, I recollect, that the curve and run of the experiment was very near to the phosphoric acid which was to be observed.  The ingredients of the lemon-lime type cola is citric acid, and other weak acids, which titrated in the same manner as the phosphoric acid.
