A A process called selective precipitation allowsfor one ion to be removed from a solution containingother ions, with only the ion of interest beingprecipitated out of solution. This process is used in thepurification of drinking water. The process occurs byselecting an ion and then carefully controlling itsconcentration in the solution.A solution contains 0.010 mol/L silver ions, Ag+ (aq),and 0.010 mol/L strontium ions, Sr²+ (aq).a. Which ion will precipitate out first when a dilutesolution of potassium chromate, K₂CrO₂(aq),is added to the mixture? (Hint: Use Ksp valuesfor the two solids that form to determine theconcentrations of chromate ion, CrO₂ (aq), neededfor each solid to form.)b. What percentage of the ion that precipitates firstwill remain unprecipitated when the second ionstarts to precipitate?

A question based on analytical separations that is to be accomplished.

Using the solution Pb(NO3)2(aq) at 2x10-3 mol/L, and Na2SO4(aq) at 2x10-3 mol/L: - give the chemical equation for the reactions if these solutions were to be mixed. - identify the ions that are present in each solution and calculate their initial concentrations (before mixing) - identify the ions that will form a precipitate when the two solutions are mixed. - If 1L of each solution are mixed, will a precipitate be formed? Why?
You have an aqueous solution containing one or more of the following anions CO3*, cr, r and SO4. When you add Ba(NO)3(aq) you get a precipitate. You separate the precipitate (A) from the supernatant (B). To the precipitate (A), you add HCI(aq) and the solution fizzes and produces a colorless, odorless gas. To the supernatant (B), you add Ag(NO)3 and there is no reaction. Identify which ions are present, might be present, or are not present Co32- A. present B. not present CI C. might be present Soą2-

b) Water "softeners" work via the principle of ion-exchange. The tank of a water softener is filled with a soluble salt such as sodium chloride. As "hard" water passes through the tank, the undesirable ions in hard water (e.g., calcium, magnesium, and iron III) are exchanged for the more desirable "soft" (meaning more soluble) ions like sodium. Explain how swapping the "soft"-water sodium ions for "hard"-water ions would influence the behavior (the cleaning effectiveness) of soaps and detergents.
One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(II) carbonate, in concentrated sulfuric acid. The sulfuric acid reacts with the copper(II) carbonate to produce a blue solution of copper(II) sulfate. Scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: Fe (s) + CuSO4 (aq) → Cu (s) + FeSO4 (aq)Suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. He adds powdered iron to a 200.mL copper(II) sulfate sample from the plant until no more copper will precipitate. He then washes, dries, and weighs the precipitate, and finds that it has a mass of 73.mg . Calculate the original concentration of copper(II) sulfate in the sample. Be sure your answer has the correct number of significant digits.
