A 1.000 ml aliquot of a solution containing Cu* and Ni* is treated with 25.00 mL of a 0.03468 M EDTA solution. The solution is then back titrated with 0.02308 M Zn* solution at a pH of 5. A volume of 20.28 ml. of the Zn solution was needed to reach the xylenol orange end point. A 2.000 ml aliquot of the Cu* and Ni* solution is fed through an ion- exchange column that retains Ni. The Cu+ that passed through the column is treated with 25.00 mL of 0.03468 M EDTA. This solution required 23.18 mL of 0.02308 M Zn* for back titration. The Ni?+ extracted from the column was treated witn 25.00 mL of 0.03468 M EDTA. How many milliliters of 0.02308 M Zn* is required for the back titration of the Ni+ solution?

A cyanide solution with a volume of 13.72 mL was treated with 25.00 mL of Ni2+ solution(which contained an excess of Ni(II) ions) to convert the cyanide to the complex ion tetracyanonickelate(II): 4CN- + Ni2+ → 6 Ni(CN)2- The excess Ni 2+ was then titrated with 10.15 mL of 0.01307 M EDTA. One mole of this reagent reacts with one mole of Ni(II) as follows: Ni(CN)42- does not react with EDTA. If 39.35 mL of EDTA was required to react with 30.10 mL of the original Ni 2+ solution, calculate the molarity of CN- in the 13.72 mL cyanide sample.
Janine's research focuses on the ability of quercetin, a flavonoid and natural dye, to detect the presence of Co2+ in wastewater samples. She prepared a set of calibration standard solutions by adding an excess of quercetin to solutions of varying Co2+ concentration and maintaining it at pH 6.4 using a Tris-HCl buffer. The reaction yields a colored complex solution that has a maximum absorbance at 440 nm:Co2+ + 2 Quercetin --> Co(Quercetin)22+ The absorbance measurements for the calibration solutions prepared are shown in the tables; a cuvette with a 2.50 cm path length was used.

A 1.000 mL aliquot of a solution containing Cu²+ and Ni²+ is treated with 25.00 mL of a 0.03169 M EDTA solution. The solution is then back titrated with 0.02152 M Zn²+ solution at a pH of 5. A volume of 15.93 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 0.03169 M EDTA. This solution required 15.86 mL of 0.02152 M Zn²+ for back titration. The Ni²+ extracted from the column was treated witn 25.00 mL of 0.03169 M EDTA. How many milliliters of 0.02152 M Zn²+ is required for the back titration of the Ni²+ solution? volume: mL
A 30-ml portion of a solution containing Ca²+ and Mg2+ was titrated with 28.19 mL of 0.207 M EDTA at pH 10. Another 30-mL aliquot of the same Ca-Mg mixture was treated with NaOH to make the solution strongly alkaline and precipitate Mg(OH)2. This solution was then titrated with the same EDTA solution. What would be the required EDTA volume (in mL) to reach the endpoint of the second aliquot if it was found that there was 0.054 M of Mg2+ in the sample? Express your answer with 2 decimal places and do not encode the units.
Chromel is an alloy composed of nickel, iron, and chromium. A 0.6392-g sample was dissolved and diluted to 250.0 mL. When a 50.00-mL aliquot of 0.05173 M EDTA was mixed with an equal volume of the diluted sample, all three ions were chelated, and a 5.15-mL back-titration with 0.06139 M copper(II) was required. The chromium in a second 50.0-mL aliquot was masked through the addition of hexamethylenetetramine; titration of the Fe and Ni required 34.27 mL of 0.05173 M EDTA. Iron and chromium were masked with pyrophosphate in a third 50.0-mL aliquot, and the nickel was titrated with 24.31 mL of the EDTA solution. Calculate the percentages of nickel, chromium, and iron in the alloy. Percentage of nickel = % Percentage of iron = Percentage of chromium = % 10
2. Titration of Ca²+ and Mg²+ in a 50mL sample of hard water required 23.65mL of 0.01205M EDTA. A second 50mL aliquot was made strongly basic with NaOH to precipitate Mg2+ as Mg(OH)2. The supernatant liquid was titrated with 14.53mL of the EDTA solution. Calculate a. concentration in ppm of CaCO3 in the sample. b. concentration in ppm of MgCO3 in the sample.

Under the same acidic conditions I. % Fe with pre-reduction II. % Fe without pre-reduction choices: -The two quantities cannot be compared due to insufficient information. -I > II -I = II -I < II
The Cl– content of a solution was analyzed via an EDTA titration. 2.00 g of AgNO3 was added to 25.00 mL of the sample solution. A titration with 0.096 53 M EDTA was then carried out, reaching an endpoint at 38.25 mL. What’s the concentration of Cl – (M)?
The Telluride ion was determined by indirect titration with EDTA. To a solution containing 50.00 mL of 0.08664M Zn(CIOA)2 plus 15 mL of 1 M acetate buffer (pH 4.5) were added 50.00 mL of unknown telluride solution with vigorous stirring. The ZnTe precipitate was filtered and washed with hot water. Then NH3 was added to the filtrate (which contained excess Zn2+) until the blue colour of Zn(NH3)42+ was observed. Titration of the filtrate with 0.07854 M EDTA required 24.22 mL to reach the murexide end point. Calculate the molarity of telluride ion in the unknown.
A 50.00 ml aliquot of a solution containing Ca2+ and Mg2+ was buffered at pH 10 and titrated with 0.0418 M EDTA. The endpoint volume was 44.36 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 0.0418 M EDTA and the endpoint volume was found to be 30.02 ml. Calculate the molar concentration of Mg.
