3. Traces of heavy metals, such as Cu* and Pb²*, in water bodies can be separated through fractional precipitation. A research work investigates the use of NaOH(aq) in separating these two ions in a 1.00 L of water sample that contains 12.70 mg Cu²* (MM = 63.546 g/mol) and 39.90 mg Pb2* (MM = 399.32 g/mol). Given: Hydroxide of Ksp Cu²+ 2.20 x 10-20 Pb2+ 1.20 × 10-15 A. Write the balanced chemical equation and the corresponding Ksp expression for the dissolution of the hydroxide salt of (a) Cu²* and of (b) Pb²* in water. B. Calculate the molar solubility of the hydroxide salt of (a) Cu²* and (b) Pb²* in water. If NaOH(aq) is added gradually to the water sample, which of the two ions is more likely to precipitate first? Explain your answer. C. Calculate the initial molar concentration of each of the heavy metal ions in the water sample.

Chlorisondamine chloride (C14H20Cl6N2) is a drug used in the treatment of hypertension. A 1.28-g sample of a medication containing the drug was treated to destroy the organic material and to release all the chlorine as chloride ion. When the filtered solution containing chloride ion was treated with an excess of silver nitrate, 0.104 g silver chloride was recovered. Calculate the mass percent of chlorisondamine chloride in the medication, assuming the drug is the only source of chloride.
One method for determining the purity of aspirin (C9H8O4) is to hydrolyze it with NaOH solution and then to titrate the remaining NaOH. The reaction of aspirin with NaOH is as follows: A sample of aspirin with a mass of 1.427 g was boiled in 50.00 mL of 0.500 M NaOH. After the solution was cooled, it took 31.92 mL of 0.289 M HCl to titrate the excess NaOH. Calculate the purity of the aspirin. What indicator should be used for this titration? Why?
Citric acid, which can be obtained from lemon juice, has the molecular formula C6H8O7. A 0.250-g sample of citric acid dissolved in 25.0 mL of water requires 37.2 mL of 0.105 M NaOH for complete neutralization. What number of acidic hydrogens per molecule does citric acid have?
