Regarding hazardous chemicals
Thread Content
I would like to ask everyone: since potassium permanganate and silver nitrate are classified as hazardous chemicals, are the standard titration solutions of potassium permanganate and silver nitrate also considered hazardous chemicals? If so, do they have the same CAS numbers?
This dilute solution is not a hazardous chemical.
One hundred percent, including potassium permanganate waste liquid
In my opinion, potassium permanganate waste liquid should be classified as hazardous waste, while the standard titration solution of potassium permanganate is not considered a hazardous chemical.
For entries in the Catalog of Hazardous Chemicals that do not specify a content level other than mixtures, this refers to industrial products or chemicals with a purity higher than that of industrial products; when used as pesticides, it refers to the active ingredient itself. Based on this understanding, the prepared standard solution is not considered a hazardous chemical.
