Instructions: Complete the following titration calculation based on the information below. Enter numerical values only into the blanks. The concentration of Cu2+(aq) ions in a solution can be determined by titration with EDTA, an aqueous solution containing the anion (Y4-) of ethylenediaminetetraacetic acid. The reaction occurs according to the equation shown below. Cu2+(aq) + y4-(aq) → CuY2-(ag) A complexometric titration was carried out where 10.00 mL samples of a solution containing Cu2+ (aq) ions was titrated with 0.01022 mol L-1 EDTA solution using a 50.00 mL burette. The volumes of -1 four titres to reach the endpoint were 23.18 mL, 23.23 mL, 23.15 mL, and 23.26 mL. mean volume EDTA used/mL 23.21 mL (2 dp) mean moles EDTA used/mol 2.372 x 10-4 mol (3 dp) mean moles Cu2+ in diluted sample/mol 1.022 x 10-4 mol (3 dp) conc.
