Title: Why would a rose turn water containing paracetamol (acetaminophen) black?
Post by: jack_ on 18/03/2019 12:05:41

Kim, a curious teacher wants to know:

During a science experiment, my student dissolved acetaminophen (also known as paracetamol) in water then put a rose in it to investigate the effect it had on the flower. The water turned black, why would this happen?

What's going on to cause this?

Maybe someone has tried this with other flowers? Did the water turn black just for the Rose, or are there other flowers that turn the water black?
