Industrial waste contains Zn(II) and cyanide. The waste is toxic to aquatic species like fish.
1- If the waste consists of water, Zn(II) and cyanide, what ligands might complex with Zn(II)?
2- Write chemical equilibria reactions the must be considered to determine toxicity of the waste?
3- How theses equations can be used to determine if industrial waste was high or low toxic?
4- Suggest another ligand that can influence the toxicity of the waste? How this ligand can affect the toxicity?
