Copper complex ion experiment with varying ligands

Experiment where ligands compete for a copper ion. Some form complex ions and some form precipitates. A brief rundown of the two reactions is discussed at the end of the experiment.
This video is for instructional purposes and the concentrations and amounts were not held constant somewhat intentionally.
Ligands include chloride, hydroxide, phosphate, oxalate, ammonia, water and sulfide.

Beautiful colors. Well presented, thanks for posting.

Could you please tell me what are the name of the solutions each containing the ligands you use in this experiments?

[@BestofBuzzYT]

does the amount or concentration of ligand matter in this experiment? If yes then how concentration and volume of each ligand have you used ? PLEASE REPLY

It won't affect the replacement, but if you add a drop of a strong ligand in a liter of solution, dilution will take place and you won't be able to see anything. If the interaction between one ligand and the metal is stronger than the other, it should be replaced. So, concentration can affect how many ligands will attach to the metal, and will affect "how much" will be affected, but won't affect if it will happen or not. I might have explained in the most confused way I possibly could, but I don't plan on becoming a teacher so wtv lol
