I've been looking for a master list of test colors. I figured I'd try out Chat GPT and below is what it coughed out after some back and forth dialog. (I'm just learning hobby chemistry so please be gentle.)
Initially the results look correct but I was hoping to have more eyes look over the results. I've learned Chat GPT results are often incorrect.
My entry text:
"Generate a list for the following metals: iron, cadmium, cobalt, nickel, tin, lead, antimony, bismuth, copper mercury, silver, gold, platinum, palladium. Add the stannous test colors and ammonia test colors to this list for each metal."

Certainly! Here's a comprehensive list for the metals you mentioned, including the Stannous test colors and ammonia test colors:
My entry text: Are these colors for nitrate salts or chloride complexes?

The colors provided in the lists are generally associated with reactions involving metal ions, whether they are from nitrate salts or chloride complexes. The colors are often observed during reactions with specific reagents, such as stannous chloride or ammonia, and the specific anion (nitrate or chloride) may not always be explicitly mentioned.
In many cases, the specific anion accompanying the metal ion can influence the behavior of the metal ion in solution, but certain tests may focus on the metal cation's characteristics rather than the accompanying anion.
For example, the Stannous test is a qualitative test that can be used to identify certain metal ions, and it involves the reaction of stannous chloride with metal ions in solution. The resulting colors are indicative of the presence of specific metal ions, and the test is not specific to a particular anion like nitrate or chloride.
Similarly, the ammonia test involves the reaction of metal ions with ammonia, forming various metal-ammonia complexes. Again, the specific anion (nitrate or chloride) is not always crucial in these qualitative tests.
In laboratory settings, the choice of reagents and the conditions of the reaction may be adjusted depending on the specific goals of the analysis.

- Cobalt (Co):
- Stannous test color: Pink
- Ammonia test color: Blue (forms Co(NH₃)₆²⁺ complex)
- Nickel (Ni):
- Stannous test color: Green
- Ammonia test color: Green precipitate ([Ni(H2O)6]²⁺ complex ion, then turns green with excess ammonia)
- Tin (Sn):
