A chemist has a solution of BaF2 containing excess BaF2 solid. Will more barium dissolve if...
A saturated solution of barium fluoride, BaF2, was prepared by dissolving solid BaF2 in water. The concentration of Ba2+ ion in the solution was found to be 7.52×10−3 M . Calculate Ksp for BaF2. The value of Ksp for silver chromate, Ag2CrO4, is 9.0×10−12. Calculate the solubility of Ag2CrO4 in grams per liter.
Part A A saturated solution of barium fluoride, BaF2, was prepared by dissolving solid BaF2 in water. The concentration of Ba2+ ion in the solution was found to be 7.52�10?3M . Calculate Ksp for BaF2. Part B The value of Ksp for silver carbonate, Ag2CO3, is 8.10�10?12. Calculate the solubility of Ag2CO3 in grams per liter.
Solid zinc phosphate and solid barium phosphate are in equilibrium with a solution containing 1.15×10-2 M barium nitrate. Calculate the concentration of zinc ion present in this solution.
Solid barium acetate is slowly added to 75.0 mL of a 0.0376 M ammonium chromate solution. The concentration of barium ion required to just initiate precipitation is ____ M. Solid barium sulfate and solid barium carbonate are in equilibrium with a solution containing 1.43×10-2 M potassium carbonate. Calculate the concentration of sulfate ion present in this solution. [sulfate] = _____ M.
Excess solid Na₂CO₃ is added to a solution containing 0.400 M (each) Mg²⁺ and Zn²⁺ ions. Ksp for MgCO₃ is 3.50 × 10⁻⁸ and Ksp for ZnCO₃ is 1.00 × 10⁻¹⁰. ZnCO₃, with the smaller Ksp, will be the least soluble and will begin precipitating first. What will be the [Zn²⁺] concentration when MgCO₃ just begins to precipitate? (Assume no volume change upon addition of the solid Na₂CO₃).
A solution is saturated with silver sulfate and contains excess solid silver sulfate: Ag2SO4(?) ⇌ 2Ag + (??) + SO4^2- (??) A small amount of solid silver sulfate containing a radioactive isotope of silver is added to this solution. Within a few minutes, a portion of the solution phase is sampled and tests positive for radioactive Ag+ ions. Explain this observation.
A chemist adds 165.0 mL of a 1.4M barium acetate (Ba(C2H3O2), solution to a reaction flask. Calculate the millimoles of barium acetate the chemist has added to the flask. Be sure your answer has the correct number of significant digits x10 mmol
Please help, I will give a huge thumbs up:) An analytical chemist is titrating 105.9 mL of a 0.7000 M solution of butanoic acid (HC3H,CO2) with a 0.5200 M solution of KOH. The pKa of butanoic acid is 4.82. Calculate the pH of the acid solution after the chemist has added 118.1 mL of the KOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of...
