We were in the ICT lab learning about chemicals when Mdm Sharizah (our Science teacher) did a little demonstration by mixing some iron fillings and copper sulfate solution. A reaction took place and the filings changed colour.
Mdm Sharizah then conducts another experiment: Mixing Potassium Iodide Solution and Lead Nitrate Solution. The result is a yellow powdery substance that has Lead Iodide and Potassium Nitrate in it.
Good thing I remembered the sites ;P
