Juan Robledo CH118-L9 5/7/09 Acid and Base Solutions 1. Water One would expect tap water to have a slightly acidic pH while the distilled water would have a neutral pH. Our results agree with these predictions. Distilled water would be healthier because it has no impurities that would make it acidic. 2. Comparison of HCl (aq) and HAc (aq) As both solutions were diluted they became more basic. HCl 0 0.5 1 1.5 2 2.5 3 3.5 0 0.05 0.1 0.15 0.2 0.25 Concentration (M)

Comparison to Calculated pH values The calculated pH and observed pH were not close to each other. This difference can be contributed to human error in measuring the dilutions. 4. The Fruit Juices The pH of the orange juice was 3.85 and the pH of the apple juice was 3.9. The orange juice was slightly more acidic. 5. Buffers...
