Say you have these A, B, and C solutions. Now you have an unknown colorless solution that contains either NaA, NaB, or NaC. In solution, each salt dissociates completely into the Na+ ion and the anion A-,B-, or C- (which are the same as this previous question). What procedure would I develop to figure out the salt present?
You must have more information than that but I can't find the other post.
I found this and it has A,B,and C in it but the two questions don't seem to be the same nor do they have any obvious connection.

To determine the salt present in the unknown colorless solution, you can use a process called selective precipitation. This procedure exploits the differences in solubility of the salts NaA, NaB, and NaC in order to identify the anion present (A-, B-, or C-).
Here's a step-by-step guide on how to perform this procedure:
1. Start by obtaining three test tubes and label them as A, B, and C, representing the three possible salts NaA, NaB, and NaC.
2. Add a small amount of the unknown colorless solution to each test tube. Make sure to add approximately equal volumes to each tube.
3. To each test tube, add an excess of a reagent that will react selectively with the anion of the corresponding salt. For example, if you suspect the presence of NaA, add a few drops of a reagent that reacts specifically with A-.
4. Observe the appearance of each test tube after the addition of the reagent. If a precipitate forms in a specific test tube, it indicates the presence of the corresponding salt.
5. Repeat steps 3 and 4 with additional reagents for the anions B- and C-. If multiple reagents result in precipitates in different test tubes, it suggests the presence of more than one salt.
6. To confirm the presence of a specific salt, you can perform confirmatory tests. These tests may involve further chemical reactions or spectroscopic techniques specific to each salt.
By following this procedure, you can determine which salt (NaA, NaB, or NaC) is present in the unknown colorless solution based on the selective precipitation of the corresponding anions.
