A solution contains one or more of the following ions: Pb²+, Ni²+, and Ba2+. When you add sodium chloride to the solution, no precipitate forms. When you add sodium sulfate to the solution, a white precipitate forms. You filter off the precipitate and add sodium carbonate to the remaining solution, producing another precipitate. Which ions were present in the original solution? Select all that apply. Pb²+ Ba2+ O Ni2+

Consider 0.0010-M solutions of these sparingly soluble solutes in equilibrium with their ions. Predict the effect on each equilibrium if a saturated solution of sodium iodide were added. Explain your prediction in each case. AgI(s) ⇌ Ag+(aq) + I−(aq) PbI2(s) ⇌ Pb2+(aq) + 2 I−(aq)
Explain the following phenomenon: You have a test tube with an aqueous solution of silver nitrate as shown in test tube l below.

A saturated solution of magenusium hydroxide is prepared and the excess solid magneusium hydroxide is settled. A 25.0 mL aliquot of the saturated solution is withdrawn and transfered to a flask, 2 dropfs of indicator are added. A 0.00053 M HCL solution is dispensed from a buret into the solution. The soution changes color after the addition of 13.2 mL. How many moles of hydroxide ion are neutralized in the analysis?
A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 303 mg of oxalic acid, a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250mL of distilled water. The student then titrates the oxalic acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 104.5 mL of sodium hydroxidesolution. Calculate the molarity of the student's sodium hydroxide solution. Round your answer to 3 significant digits.

The answers to the questions are already given. Please show the solution how to get the answers. A solution containing 0.5 mM CO32- and 2.5 mM F- is to be separated using Mg(NO3)2 as precipitating agent. Ksp of MgCO3=3.5x10-8. Ksp of MgF2=3.7x10-8. Which ion will precipitate first? Answer: CO32- How much of the first ion (in M) will be left when the second ion starts to precipitate? 5.91x10-6 M
Cd+2 and Fe+2 (starting concentration 10 mol/L) should be separated by fractionated precipitation using H₂S. Does a pH range exist allowing to completely precipitate one metal (i.e. the remaining concentration of the precipitated ion has to be 10 mol/L or less) whereas the other stays in solution at its initial concentration? Please calculate this pH range whereby pH values below zero are set to zero! Please illustrate the situation graphically by plotting pH versus in solution/precipitating/fully precipitated for the two ions
