In the laboratory you are given the task of separating Ba2+ and Zn2+ ions in aqueous solution.For each reagent listed below indicate if it can be used to separate the ions. Type "Y" for yes or "N" for no. If the reagent CAN be used to separate the ions, give the formula of the precipitate. If it cannot, type "No" Y or N Reagent Formula of Precipitate if YES Example: Y NaOH Zn(OH)2 A. KBr   B. Na2CO3

Complete the table below by deciding whether a precipitate forms when aqueous solutions A and B are mixed. If a precipitate will form, enter its empirical formula in the last column. Does a precipitate form when A and B are mixed? empirical formula of precipitate solution A solution B barium bromide sodium chloride O yes no copper(II) bromide sodium hydroxide O yes no potassium sulfide lead(II) nitrate yes O no

A scientist is investigating the solubility of two polyatomic ions, oxalate (C2O2−4C2⁢O42−) and arsenate (AsO3−4AsO43−), 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 A Na3AsO4Na3⁢AsO4 colorless B (NH4)2C2O4(NH4)2⁢C2⁢O4 colorless C AgClO3AgClO3 colorless D AlBr3AlBr3 yellow The results of mixing each solution in pairs are shown in the table. Experiment Solutions Mixed Result 1 A + B no precipitate, colorless solution 2 A + C brown precipitate 3 A + D white precipitate 4 B + C white precipitate 5 B + D white precipitate 6 C + D yellow precipitate Identify the formula for each precipitate that forms. precipitate from A+C:   precipitate from A+D:   precipitate…
