    The results of these steps are summarized in the flow chart below. The addition of HCl in the second step fails to dissolve BaSO 4 since SO 4 2-is the anion of a strong acid. Other anions also form insoluble precipitates with barium ions such as BaCO 3, BaSO 3, and Ba 3(PO 4) 2. However, theses are salts of weak acids and will all dissolve in ...

    CATION GROUP SEPARATION INTRODUCTION. Qualitative analysis is a procedure for identifying substances in a mixture. In this experiment you will be identifying cations present in a solution. These ions are identified by specific chemical tests but because one cation can interfere with a test for another ion, the ions must first be separated.

    Group 1: HCl is added to the soluble nitrate salts of the metal ions (rule 1) to precipitate AgCl (rule 2). Group 2: Addition of NH 3 (also known as NH 4 OH) makes the solution basic and precipitates the hydroxide of Fe 3+ (rule 5). A portion of the added NH 3 reacts with the HCl from the first separation to form NH 4 1+ (ammonium cation), forming a buffer solution with the unreacted NH 3.

    3. The first type of metathesis reaction is a precipitation reaction. In these, a solid, non-soluble product is formed. It occurs when two soluble ionic compounds are mixed together, they exchange partners and one of the products is an insoluble compound so it drops out of solution as a solid. An example of a precipitation reaction from this lab is (NaCl + AgNO3 --> NaNO3 + AgCl).
