A scientist is investigating the solubility of two polyatomic ions, oxalate (C₂02) 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. Solute Color of Solution Na, AsO4 colorless (NH,),C,O. colorless colorless AgCIO, AlBr yellow The results of mixing each solution in pairs are shown in the table. Experiment Solutions Mixed 1 A + B 2 A+C 3 A+D B+C B+D C+D Solution A B C D 4 5 6 Identify the formula for each precipitate that forms. precipitate from A+C: precipitate from B+C: 2 Incorrect precipitate from C+D: 4 Incorrect 6 Result no precipitate, colorless solution brown precipitate white precipitate white precipitate white precipitate yellow precipitate Incorrect precipitate from A+D: precipitate from B+D: 3 Incorrect 15 Incorrect
