Hi there,
I'm doing an investigation into the behavior between Mercuric Oxide and soil. I really need a way to determine, in a sample of water in which water has been run through Mercuric Oxide, whether or not any has remained within the sample. Whether this be through changing pH levels, or a simple test with reactions, I really need some advice. I have an entire chemistry lab worth of resources, so any help would be gladly appreciated.
