What is the final concentration of an EDTA solution if 10 mLof 0.01 M EDTA solution...
To determine the Ca^2+ concentration in water sample, a standard EDTA solution of 0.01988 M was used to titrate 25 ml. of the sample solution with the presence of an ammonium buffer (pH 10). If 15.80 ml. of the standard EDTA was used to reach the end point, calculate the molar concentration and the ppm concentration of the unknown Ca^2+ (atomic weight of Ca = 40.08g/mole) solution The amount of 0.2915g of benzoic acid was dissolved in 100 ml. of...
QUESTION 4 A 500.0 mL water sample is titrated with 15.00 mLof 0.1040 M EDTA. How many mg of Caco3 are in the sample?
4. 50.0 mL of 0.00200 M Ca2 solution buffer at pH 10.0 is titrated with 0.00200 M EDTA. At equivalence point (i.e. 50.0 mL EDTA has been added), what is the equilibrium concentration of Ca2, [Ca2], and what is the pCa? The formation constant of CaY, Kaa 5.0 x 1010, and α4 of EDTA at pH 10.0 is 0.35
4. 50.0 mL of 0.00200 M Ca2 solution buffer at pH 10.0 is titrated with 0.00200 M EDTA. At equivalence point...
A 25.0 mL aliquot of 0.0440 M EDTA was added to a 49.0 mL solution containing an unknown concentration of V3+. All of the V3+ present in the solution formed a complex with EDTA, leaving an excess of EDTA in solution. This solution was back-titrated with a 0.0340 M Ga3+ solution until all of the EDTA reacted, requiring 11.0 mL of the Ga3+ solution. What was the original concentration of the V3+ solution?
CALCIUM HARDNESS DETERMINATION Fill a 50 mL burette with 0.01 M EDTA solution, making sure the tip is full and free of air bubbles. Set Start volume. Add 50.00 mL of an unknown hard water solution into a 100 mL beaker. Obtain Magnetic Stirrer from Equipment menu. Place beaker on stirrer. Increase Stir from the context menu. Add 4 mL of 1.0 M Sodium Hydroxide. Add 100 mg of Murexide indicator. Titrate with the 0.01 M EDTA until the color...

What is the Co2+ concentration after 50 mL of a 0.030 M Co2+ solution is mixed with 50 mL of a 0.050 M EDTA solution at pH 10?
What is the final concentration of a solution made from 7.1 mL of 0.82 M CuSO4 and 12.9 mL of water? Express answer as a decimal with two decimal places. Do not include units.
Calculate the concentration of an EDTA solution of which 24.22 mL were needed to titrate the Ca2+ ions present in a 50.00 mL solution containing 246.7 mg CaCO3. Express your answer in terms of (a) molar concentration of EDTA and (b) Ca titer (mg Ca per mL of EDTA)
