Phenolphthalein was the indicator you used in your titration. a. What made phenolphthalein a good choice of indicator? (Meaning, how do you choose an appropriate indicator for a titration.) b.You used only a couple drops of a 1% solution. Why is it important to use such a small quantity of indicator in a titration? c.The point where the color changed is known as the end point. What is the difference between the end point and equivalence point? d.Can the end...

The Fajans titration uses an adsorption indicator to detect the endpoint of a titration in which a precipitate is formed. For the titration of Cl by Ag insoluble AgCl is formed. Indicate what is happening at each step of the titration by selecting the correct statement. (a) During the titration:Ag solution was added to Cl solutionCl solution was added to AG solution. (b) At the endpoint, just past the equivalence pointAn excess of Cl

On the indicators of faecal contamination in the waters: A. Define what is an indicator of faecal contamination and the characteristics of an ideal indicator. Differentiate between a fecal and a process indicator. b. Select four indicators of fecal contamination and discuss them. Mention advantages and disadvantages of these methods. c. If you want to determine if a water sample related to a lentic system is contaminated with human fecal material what indicators would you use, explain.
