Flowchart :
Match the statement to the correct answer. (Some reagents can be used more than once.) The flowchart along with the report sheets in experiment 5 should be very helpful.

In test B2 this reagent is added to tests after a precipitate is formed. Salts containing these ions are nearly always soluble in water. In test B1 this is the first reagent added to the sample. The name for a positively charged ion is.... Concentrated Ammonia (NH_3) will combine with water to form these ions in solution. Cation Flowchart (mix well after adding each reagent): Anion Flowchart (mix well after adding each reagent):Explanation / Answer
(1)
