- 4.50 mL of 0.1 M Ca2+ ion was titrated at pH 10 with 0.1 M EDTA. What will be the concentration of Ca2+ ions in the solution when 25 mL, 50 mL and 75 mL EDTA is added(a4 = 0.35, Kf = 5.0x1010)?vity/Student Guide Big Idea Assessments A certain brand of zinc cold medicine is marketed as containing 5.0 mg of zinc in every lozenge. A student team decides to test this claim with a complexometric titration. Xylenol orange forms a red complex with zinc ions, but is yellow when it is free. EDTA is able to form much stronger complexes with zinc ions. For their analysis, the students dissolve one colorless lozenge in a small amount of buffer. They add a few drops of the xylenol orange indicator, then titrate with EDTA. The end point is achieved with 19.36 mL of EDTA. 1. How do the students know when the end point is achieved? Describe what happens to the substances involved in the reaction when the end point is achieved. Explain any observations that may be noted by the students. 2. What concentration of EDTA should the students use so that approximately 25 mL of titrant would be needed to reach the end point if the lozenge contained the 5.0 mg of zinc claimed by the manufacturer? 3.…Concerning EDTA titrations, which of the following is incorrect? 1. OEDTA forms 1:1 complexes with metal ions. 2. OThe most widely used indicators are murexide and Eriochrome Black T. 3. Oln presence of NaOH, EDTA reacts only with Mg2 ions, using murexide indicator. 4. OThe water hardness is usually expressed as CACO3 mg /L water. 5. OEDTA solution was standardized using Zinc Sulfate.
- Several common masking agents used in EDTA titrations are listed paired with a mixture of two metal ions. Classify each masking agent-metal ion combination by whether the masking agent is capable of masking one of the metal ions and still allowing the other metal ion to react with EDTA or not. Masks one metal ion but not the other triethanolamine: Al³+ and Pb²+ fluoride: Al³+ and Fe³+ cyanide: Ca²+ and Mn²+ Answer Bank cyanide: Ni²+ 2,3-dimercapto-1-propanol: Bi³ + and Pb²+ Does not mask or masks both metal ions and Pb²+ fluoride: Tit+ and Cd²+A 50.00 mL aliquot of standard CaCO3 (0.3834g CaCO3 per liter) consumed 42.35 mL of EDTA solution. The same EDTA standard solution was used for the titration of a 3.00 mL water sample. This required 30.56 mL of the titrant. Calculate the molar concentration of EDTA standard solution. What is the total hardness of water sample (then after solving explain how it come up to the final answer.)The Ksp of the salt MC204 was determined by titration with potassium permanganate. The balanced net ionic reaction for this titration reaction is shown below. 2MnO4 +5C₂04² + 16H* --> 2Mn²+ +10CO2 + 8H₂O If a 50.00 mL saturated solution of MC₂04 requires 1.49 mL of a 0.000520 M solution of potassium permanganate, what is the Ksp for MC₂04? Enter your answer using scientific notation like this: 10,000 = 1*10^4.
- The titration of Zn+2 and EDTA is carried out in the same manner as Mg2+ - EDTA titration (in fact, Zn metal may be used to standardize your EDTA solution). In this case, the ammonia from the pH 10 buffer serves and additional purpose other than the deprotonation of EDTA. What is it? pH 10 buffer is made with 57 mL of concetrated NH3 (or NH4OH) and 7 g of NH4Cl and diluted to 100 mL with DI waterthe amount of iron present in a compound was analyzed based on a titration with EDTA. Iron (III) forms a complex ion with EDTA according to the following balanced equation: Fe3+ + EDTA ⇌Fe(EDTA)3+ If 27.22 mL of 0.065M EDTA are used in the titration reaction, how many moles of Fe3+ reacted? You must give your answer in exponential notation with two decimal places. Example: 2.33e-4Calculate pFe2+ at each of the points in the titration of 25.00 mL of 0.02045 M Fe2+ by 0.03584 M EDTA at a pH of 7.00. The values for log Kf and aya- can be found in the chempendix. 13.00 ml pFe2+ the equivalence point, V. pFe2+ = 17,50 mL pFe?+
- To determine the concentration of Ni2+ in an unknown solution, a known excess of EDTA is added to the solution. The pH is then adjusted using an appropriate buffer. Finally, the excess EDTA is back-titrated with a standard Zn2+ solution. What pH range should the solution be buffered to if xylenol orange is used as the indicator? O pH 11–12 O РH 9-10 O pH 5-6 O pH 7-8 What color change will be observed at the end point? O red to violet O red to yellow O violet to red yellow to redA solution containing 60 mL of a 0.025 mol / L metal ion (Mn +) buffer buffered to pH 7.0 was titrated with a 0.05 mol / L EDTA solution. Data: Conditional formation constant (Kf)=10^15. Determine: i) The concentration of the free metal when ½ of the equivalence volume is added. ii) the concentration of free metal in the equivalence volume. iii) the concentration of free metal with an excess of 2 mL of EDTA? (Data - EDTA constants: K1=0.01; K2=2.19.10^-3; K3=6.92.10^-7; K4=5.75.10^-11)In which of these situations is it necessary to perform an EDTA back titration instead of a direct titration? The analyte precipitates in the absence of EDTA. The formation constant of the metal-EDTA complex is small. The analyte blocks the indicator. The color of the free indicator and metal-indicator complex are too similar.
