- A solution contains 0.00740 M calcium ion. A concentrated sodium fluoride solution is added dropwise to precipitate calcium fluoride (assume no volume change). a At what concentration of F does precipitate start to form? b When [F] = 9.5 104 M, what is the calcium-ion concentration? What percentage of the calcium ion has precipitated?arrow_forwardA solution contains 0.0150 M lead(II) ion. A concentrated sodium iodide solution is added dropwise to precipitate lead iodide (assume no volume change). a At what concentration of I does precipitate start to form? b When [I] = 2.0 103 M, what is the lead-ion concentration? What percentage of the lead(II) originally present remains in solution?arrow_forwardHow would the solubility of calcium fluoride be affected by the presence of fluoride ion from another source?

Calculate its molar solubility in water and its Ksp.arrow_forwardAn analytical chemist has a solution containing chloride ion, Cl. She decides to determine the amount of chloride ion in the solution by titrating 50.0 mL of this solution by 0.100 M AgNO3. As a way to indicate the endpoint of the titration, she added 1.00 g of potassium chromate, K2CrO4 (see Figure 17.5). As she slowly added the silver nitrate to the solution, a white precipitate formed. She continued the titration, with more white precipitate forming. Finally, the solution turned red, from another precipitate. The volume of the solution at this point was 60.3 mL. How many moles of chloride ion were there in the original solution? How many moles of chloride ion were there in the final solution? You may make any reasonable approximations.arrow_forward

Calculate Ksp at this temperature.arrow_forwardSolubility Equilibria Consider three hypothetical ionic solids: AX, AX2, and AX3 (each X forms X). Each of these solids has the same Ksp value, 5.5 10 7. You place 0.25 mol of each compound in a separate container and add enough water to bring the volume to 1.0 L in each case. a Write the chemical equation for each of the solids dissolving in water. b Would you expect the concentration of each solution to be 0.25 M in the compound? Explain, in some detail, why or why not. c Would you expect the concentrations of the A cations (A+, A2+, and A3+) in the three solutions to be the same? Does just knowing the stoichiometry of each reaction help you determine the answer, or do you need something else? Explain your answer in detail, but without doing any arithmetic calculations. d Of the three solids, which one would you expect to have the greatest molar solubility? Explain in detail, but without doing any arithmetic calculations. e Calculate the molar solubility of each compound.arrow_forwardA saturated solution of a slightly soluble electrolyte in contact with some of the solid electrolyte is said to be a system in equilibrium.
