5. What reagent will precipitate? (a) Cu2+ but not Ba2+? (b) Ag+ but not Ca2+? (c)...
What chemical is used to separate Ca2+ and Ba2+ ions from a solution containing Ca2+, Ba2+, NH4+, and K+ ions? What are the products of the Ca2+ and Ba2+ ions with this chemical?
1). What solution (anion) can you add to each of the following cation mixtures to precipitate one cation while keeping the other cation in solution? (refer the solubility table) a). Ba2+ (aq) and Mg2+ (aq) b). Cu2+ (aq) and Hg22+ (aq) c). NH4+ (aq) and Ca2+ (aq) d). Fe2+ (aq) and Pb2+ (aq) e). Ag+ (aq) and Zn2+ (aq) Can someone explain to me, in simple terms, how these problems are solved?
D Question 5 5 pts A solution contains Ba2+, Hg2+, Ag+ NH4+, and Fe2+ Identify the precipitate after the addition of 6 M HCI. O NH4Cl Hgs Ba3(PO4)2 OAgci Fes
A solution contains one or more of the following ions: Ag+1, Ca2+, and Cu2+. When sodiumchloride is added to the solution, noprecipitate forms. Whensodium sulfate is added to the solution, a white precipitate forms.this precipitate is filtered off and sodium carbonate is added tothesolution, which also produces a precipitate. Which ions werepresent in the original solution.HELP

Consider a solution that is 1.3×10−2 M in Ba2+ and 1.8×10−2 M in Ca2+. Ksp(BaSO4)=1.07×10−10 Ksp(CaSO4)=7.10×10−5 *Part A: If sodium sulfate is used to selectively precipitate one of the cations while leaving the other cation in solution, which cation will precipitate first? If sodium sulfate is used to selectively precipitate one of the cations while leaving the other cation in solution, which cation will precipitate first? A) Ba2+ (ANSWER) B) Ca2+ *Part B: What minimum concentration of Na2SO4 is required...
Ex: Separation of Group 1 Cations (Pb+ and Ag+) 10 drops of unknown was place along with 6 drops of 6M HCl, centrifuge. 2 more drops of 6M HCl, centrifuge. Decant supernate, use precipitate and add 5 drops of cold water, centrifuge. Test for Pb2+ 15 drops of water to precipitate & put in hot water, centrifuge then decant supernate. repeat x2 Combine supernates and save precipitate for Ag+ analysis. Add 3 drops of 1M K2CrO4 to supernate. yellow precipitate...
A solution contains 0.10 M concentrations of Ba2+, Ca2+, and Sr2+. Na2CO3 is slowly added to the solution. In what order will the ions begin to precipitate? What is the concentration of the first ion when the 2nd begins to precipitate? Ksp for BaCO3 = 2.58 x 10-9, for CaCO3 = 3.36 x 10-9, and for SrCO3 = 5.60 x 10-10.
