Abstract:
This labaratory report shows that when presented with an unknown chemical substance, identification of that substance is revealed through a seires of tests that involve chemical and physical properties of that substance.
Problem:
You are given an unknown chemical substance that you need to be able to identify. How are you going to do this? The compound can be either harmful or toxic, so what you need to do is test all of its physical and chemical properties, and then find out the synthesis of the substance. Qualitative testing and quantitative testing is essential in discovering what the unknown is.

Anion Percipitate Test #1
1. For the first percipiate test with my unknown H chemical, I mixed it with , or Lead (III) nitrate. The purpose of this test was to determine whether my unknown formed a percipitate with Lead (III) nitrate, and to eliminate anions.
2. If the reaction with is soluble, it would allow me to narrow down my options to fewer suspected anions. Since only a few anions formed percipitates with Lead (III) nitrate according to my table of solubilities, it would be easier to eliminate anions.
3. This test requires a spot plate cleaned
