Question
The determination of chloride ion in your water sample was performed using the Mohr method of titration (using potassium chromate as indicator.) Use a scientific encyclopedia or online reference to describe two other titration methods for the determination of chloride ion. Describe the reagents used in these titration methods and how the methods differ from the Mohr method EDTA is used for many purposes in addition to analysis of calcium in water. Use a chemical encyclopedia or the internet to list four additional uses of EDTA (Na_2H_2EDTA).
Explanation / Answer
Answer:-
1. The two other methods which are used for chloride ion analysis in water are as,
a. Fajan's method , which involves the indicator of fluorescein and dichlorofluorescien.
b. Volhard method, it involved Fe(III) salt as an indicator ot tatrazine(0.5% aq. solution).
2. Four uses of EDTA
a. It is used in complexometric titration.
b. It is used as a chelating agent.
c. For the formation of complex compound.
d.EDTA can also be used for the determination of other metals such as Ni, Zn,etc
