Determine the concentration of an HBr solution if a 55.00 mL aliquot of the solution yields 0.6643 g AgBr when added to a solution with an excess of Ag ions. The Ksp of AgBr is 5.0
Homework Answers
Mol wt of AgBr = 187.7
moles of AG = 0.6643/187.7 = = 0.00354
=> moles of Br = = 0.00354
and molarity = = 0.00354/0.055 = 0.06436 M

A 24.34 mL aliquot of a Pb2 solution, containing excess Pb2+, was added to 11.50 mL of a 2,3-dimercapto-1-propanol (BAL) solution of unknown concentration, forming the 1:1 Pb2+-BAL complex. The excess Pb2+ was titrated with 0.0157 M EDTA, requiring 9.88 mL to reach the equivalence point. Separately, 39.89 mL of the EDTA solution was required to titrate 32.75 mL of the Pb2+ solution. Calculate the BAL concentration, in molarity, of the original 11.50 mL solution concentration:

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?

A 25.0 mL aliquot of 0.05600.0560 M EDTAEDTA was added to a 40.040.0 mL solution containing an unknown concentration of V3+V3+. All of the V3+V3+ present in the solution formed a complex with EDTAEDTA, leaving an excess of EDTAEDTA in solution. This solution was back-titrated with a 0.03300.0330 M Ga3+Ga3+ solution until all of the EDTAEDTA reacted, requiring 10.010.0 mL of the Ga3+Ga3+ solution. What was the original concentration of the V3+V3+ solution?

A titration was performed to standardize an EDTA solution. a) A 25.00 mL aliquot of a standard solution containing 0.01500 M Ca2+ required 42.87 mL of EDTA to reach the endpoint. The molarity of the EDTA solution is: ________ M b) That same EDTA solution was then used to titrate an unknown hard water sample. A 40.00 mL aliquot of unknown hard water required 34.21 mL of EDTA solution to reach a distinct endpoint. The concentration of Ca2+ ions (assuming...
