1. Describe the function of the phenolphthalein in this experiment. How would this experiment be different if you had forgotten to add the phenolphthalein  

2. Environmental studies usually involve an analysis of precipitation and its response to pollution. To quantify the degree of contamination in natural rain water or snow, titration is used. The process is quick and results are reliable. Since most utration processes do not require espera Specialized equipment, the test can be performed often and in different areas with relatively to effort 2. 

a. 1000.0 ml sample of lake water is titrated using 0.100 mL of a 0.100 M base solution. What is the molarity of the acid in the lake water.

b. Based on the molarity of the acid calculated above, what is the pH of the lake water?
