This video is about the AP Chemistry Laboratory – Experiment #2:
Physical & Chemical Changes.
In this video you will watch a series of six experiments where some of them show physical changes and the others show chemical changes.
The experiments are:
1- Mixing copper wire with silver nitrate.
2- Mixing sodium chloride with water, evaporating water, or adding silver nitrate to an aqueous solution of sodium chloride.
3- Heating cobalt chloride hexahydrate.
4- Sublimation of Iodine crystals.
5- Mixing Magnesium ribbon with copper (II) sulfate.
6- Mixing copper wool with nitric acid.
