QUESTION 6 A hypothetical metal ion M forms a 1:1 stable complex with EDTA and the re 3/21 constant is equal to 10 Mat pH - 13.17 (this is the pH at which the titration Using this information, answer the following questions: Calculate the free uncomplexed concentration of the metal ion M at the equivalence point when the complexometric titration is performed with a 0.0082 M solution of EDTA. The titrant volume at the equivalence point is equal to 0.0531 L. You also know that the initial 6(a) volume of the metal sample solution is equal to 17.6 ml. Will the result of your calculations in question 6(a) change, if the titration is performed in a buffer with pH of 6.907 Provide reasons(s) for your answer. 6(b) [2)
