A+C =>
Na3AsO4 + 3 AgClO3 ------------> Ag3AsO4 (s) + 3 NaClO3 (aq)
here the precipitate is Ag3AsO4
B+C =>
(NH4)2C2O4 + 2 AgClO3 ----------> Ag2C2O4 (s) + 2 NH4ClO3(aq)
here the precipitate is Ag2C2O4
C+D =>
3 AgClO3 + AlBr3 --------------> 3 AgBr (s) + Al(ClO3)3 (aq)
here the precipitate is AgBr
A+D =>
Na3AsO4 + AlBr3 --------------> AlAsO4 (s) + 3 NaBr (aq)
here the precipitate is AlAsO4
B+D =>
3 (NH4)2C2O4 + 2 AlBr3 -------------> Al2(C2O4)3 (s) + 6 NH4Br (aq)
here the precipitate is Al2(C2O4)3

Question 5 of 15 > A A scientist is investigating the solubility of two polyatomic ions, oxalate (CO) and arsenate (Aso ), which are not listed in the table of solubility guidelines. The scientist starts with four solutions made of water-soluble salts. Solution A contains sodium arsenate. Solution B contains ammonium oxalate. Soution C contains silver chlorate. Solution D contains aluminum bromide. Solution Solute Color of Solution Na Aso, colorless B : (NH),C,0 colorless AgClo, colorless AlBr yellow The results...

"Hard" water contains mainly salts of Ca2+ and Mg2+, both of which form many insoluble salts. You have a water sample and need to determine whether it contains Ca2+ and/or Mg2+. When you add ammonia to the solution, followed by ammonium chloride and ammonium oxalate, a white precipitate of CaC2O4 should form if Ca2+ is present. What is the purpose of adding the ammonium chloride to the reactant mixture? a. The chloride ion helps to form the calcium chloride precipitate....

1. For each of the descriptions of different solutions, what inferences can be made? (Which ion(s) are identified as possibly present, confirmed present, absent, or no conclusion?) a. Hot water was added to a white precipitate (AgCl and/or PbCl2). After stirring, the precipitate completely dissolved forming a colorless solution. b. Aqueous ammonia was added to a solution (Cu2+ and/or Bi3+). After stirring, a white precipitate formed, with a colorless solution above it.b. c. HCl was added to Group 1 and...

You are given a colorless unknown solution that contains one of the following salts: NaA, NaB, NaC. in solution, each salt dissociates completely into the Na+ ion and the anion A-,B- or C-, whose properties are given ( B2 weakest oxidizing agent, then C2, then A2 the strongest oxidizing agent) The Na+ ion is effectively inert. Given the availability of solutions of A2,B2, AND C2, develop a simple procedure for IDing the salt that is present in your unknown.

Anion analysis
POSTLABORATORY ASSIGNMENT 1. An iodide/chloride/sulfate unknown solution gave a yellow precipitate with AgNO The supernate did not react with Ba(NO)). The yellow precipitate did not dissolve in NH, H,O. After centrifuging the supernate was acidified with HNO, and gave a white precipitate. State the ion(s) present in the unknown solution. An iodide/chloride/sulfate unknown solution plus AgNO, gave no reaction. The solution was treated with Ba(NOs)2 and produced a white precipitate. State the ion(s) present in the unknown solution....
