I just bought a flame-test spectroscopy kit to use with our small homeschool group. It includes calcium chloride, potassium chloride, strontium chloride, and lithium chloride. I also bought a bottle of copper chloride.
After we do the lab, how can I safely dispose of the solutions? Can I just dilute the solutions and flush them? Or do they require a Hazardous Material Pickup?
Thanks in advance!
