A 1.000 mL aliquot of a solution containing Cu²+ and Ni2+ is treated with 25.00 mL of a 0.03835 M EDTA solution. The solution is then back titrated with 0.02240 M Zn²+ solution at a pH of 5. A volume of 15.56 mL of the Zn2+ solution was needed to reach the xylenol orange end point. A 2.000 mL aliquot of the Cu²+ and Ni²+ solution is fed through an ion- exchange column that retains Ni²+. The Cu²+ that passed through the column is treated with 25.00 mL of 0.03835 M EDTA. This solution required 19.69 mL of 0.02240 M Zn²+ for back titration. The Ni²+ extracted from the column was treated witn 25.00 mL of 0.03835 M EDTA. How many milliliters of 0.02240 M Zn²+ is required for the back titration of the Ni²+ solution? volume: mL

A 14.92 g sample of bacon is pureed in a blender with 100.0 mL of water. The suspension is filtered and the clear solution containing dissolved sodium nitrite is adjusted to pH 2. The solution is treated with 25.0 mL of 0.0150 M KMnO4 to oxidize the nitrite to nitrate and after standing for 10 minutes, the excess KMnO4 is back titrated with 15.0 mL of 0.0818 M FeSO4. What is the concentration of nitrite in the bacon as parts per million?
In order to adjust the EDTA solution, 10 mL of 0.01M Ca + 2 sample was taken and 10 mL of pH 10 buffer was added on it and it was completed to 100 mL. Then, two drops of EBT indicator were added and titrated with EDTA. Since the consumption is 13 mL, what is the concentration of EDTA solution in terms of molarity?
For complexometric titration of Ca (II) ions in the shell of an egg sample weighing 59,427 g, the necessary processes were applied to the egg shells and a sample of 100 mL was prepared. From the prepared sample, 1 mL was taken and diluted to 100 mL, the pH was adjusted, and two drops of EBT indicator were dripped on it. The prepared solution was titrated with 27.4 mL of EDTA solution set at 0.0097 M. Calculate the amount of calcium in the sample in CaCO3%. (Ca = 40g / mol, CaCO3= 100g / mol)
A 50.00 ml aliquot of a solution containing Ca2+ and Mg2+ was buffered at pH 10 and titrated with 0.0474 M EDTA. The endpoint volume was 40.99 ml. A second aliquot of the same mixture was made strongly basic by the addition of NaOH – this causes the Mg2+ to precipitate as Mg(OH)2. The solution was then titrated with the 0.0474 M EDTA and the endpoint volume was found to be 30.04 ml.
A 0.4071-g sample of pure CaCO3 was transferred to a 500-mL volumetric flask, dissolved using a minimum of 6 M HCl, and diluted to volume. After transferring a 50.00-mL portion of this solution to a 250-mL Erlenmeyer flask, the pH was adjusted by adding 5 mL of a pH 10 buffer. After adding an indicator, the solution was titrated with the EDTA, requiring 42.63 mL to reach the end point. What is the concentration of EDTA? Choices: 0.0191 M, 0.0955 M, 0.00955 M, 0.477 M
