Purpose: The purpose of this experiment is to investigate the acidic and basic properties of several aqueous solutions and to determine the pH of these various solutions. This will be done through the use of litmus paper and pH meter. Procedure: composition book pages 14-15 Data: see attached Calculations: Summary of Results: Test Tube Solution Neutral Litmus(Red or Blue) pH Hydrogen Ion Concentration 1 Lemon Juice Red 2.50 2 Oxiclean Blue 8.63 3 Diet Pepsi Red 3.05 4 White Vinegar Red 2.55 5 Bleach Blue 12.41 6 Ammonia Blue 11.71 7 Budweiser Red 4.50 8 0.01M HCl Red 2.32 9 0.01M CH3COOH Red 3.27 10 0.1M HCl Red 1.36 11 0.1M CH3COOH Red 2.78 Conclusion: The purpose of this lab was to determine whether certain household products

The purpose was achieved and one source of error that could have occurred was when calibrating the calibration processed could have been messed up a little. Also another source of error could be not waiting until the pH level had fully stabilized before recording down the pH reading from each of the solutions. Lastly the calculations could have been done wrong or they were not brought out to the right decimal places....
