Murder Lab

This lab was about a theoretical murder case where the victim was poisoned with an unknown chemical. The goal was to find what the chemical was, either potassium iodine or silver nitrate (the victim was violently allergic to potassium iodine and silver nitrate is poisonous when swallowed) and who poisoned the victim.

We found our what the chemical was by combining the mystery solution with sodium carbonate and seeing whether a chemical reaction was caused or not. It did occur so we could assume that mysterious compound was silver nitrate. Then we drained the solution in filter paper and let it out to dry.

All I have to do to complete the lab is find the molarity of the silver nitrate and use that to find the killer.
