Solubility Question Help

[Chemkid]

• A chemist prepares four beakers, each with exactly 1.0 M of a
particular salt dissolved in water. In the reactions, assume
complete formation of any solid products (ignore equilibrium).
• Step 1: The silver nitrate solution is poured into the
ammonium bromide solution. What (if any) precipitate forms?
• Step 2: Sodium sulfate solution is poured into the aqueous
part of the Step 1 mixture. What (if any) precipitate forms?
• Step 3: Barium chloride solution is poured into the aqueous
part of the Step 2 mixture. What (if any) precipitate forms?
• Step 4: Identify all the ions that remain dissolved in the
solution when all the precipitation reactions are finish
This is from a hw problem I have any help would be appreciated

This really is made on paper not as a experiment.
1. Silverbromide will precipitate.
2. It also precipitate, can be Calcium, Strontium or Barium as sulfate.
3. Now the Joke comes. Sulfate was poured in step 2 first, if you put Bariumchloride in of coures Bariumsulfate will precipitate again.
4. Count by yourself what is left.
