Below are sample questions representative of the exercises included on this worksheet and related 11.73 Solution Stoichiometry and Titration Stoichiometry skill assessments:

Problem 1Difficulty: Mastery

A 10.00 mL solution containing Cu2+ is treated with excess iodide, producing I2 that requires 18.00 mL of 0.100 M Na2S2O3. If 2Cu2+ + 4I- -> 2CuI + I2 and I2 + 2S2O3²- -> 2I- + S4O6²-, what is [Cu2+]?

A0.0900 M Cu2+

B0.360 M Cu2+

C0.0180 M Cu2+

D0.180 M Cu2+

Solution & Explanation:Thiosulfate moles are 0.100 x 0.01800 = 0.00180 mol, so I2 = 0.000900 mol. The copper reaction gives 2 mol Cu2+ per 1 mol I2, so Cu2+ = 0.00180 mol in 0.01000 L, or 0.180 M.

Problem 2Difficulty: Mastery

A 0.5000 g impure Ca(OH)2 sample requires 38.40 mL of 0.200 M HCl. For Ca(OH)2 + 2HCl -> CaCl2 + 2H2O, what is the percent Ca(OH)2 in the sample? Use molar mass Ca(OH)2 = 74.09 g/mol.

A113.8% Ca(OH)2

B28.4% Ca(OH)2

C56.9% Ca(OH)2

D38.4% Ca(OH)2

Solution & Explanation:Moles HCl = 0.200 x 0.03840 = 0.00768 mol. Ca(OH)2 moles are half, 0.00384 mol. Mass Ca(OH)2 = 0.00384 x 74.09 = 0.2845 g; percent = 0.2845/0.5000 x 100 = 56.9%.

Problem 3Difficulty: Mastery

What volume of 0.0200 M MnO4^- is required to titrate 25.00 mL of 0.0600 M Fe2+ in acid? Use MnO4^- + 5Fe2+ + 8H+ -> Mn2+ + 5Fe3+ + 4H2O.

A75.0 mL MnO4^-

B15.0 mL MnO4^-

C3.00 mL MnO4^-

D25.0 mL MnO4^-

Solution & Explanation:Fe2+ moles = 0.0600 x 0.02500 = 0.00150 mol. MnO4^- moles are one-fifth as many, 0.000300 mol; V = 0.000300/0.0200 = 0.0150 L = 15.0 mL.
