Powder Analysis :
In this experiment, you conduct various tests on the powder that was found from the crime scene.
The various tests are:
Appearance: Examine what each powder looks like. How would you describe the powder’s shape (crystalline/amorphous)? For e.g. Sugar is crystalline.
Texture: Examine the powders further by rubbing each powder between your fingers. For e.g. Flour is smooth.
Smell: Determine if there is a smell to any of the powders. For e.g. Talc has a particular smell.
Water solubility test: Dissolve some of the white powder in water and observe its solubility. For e.g. Salt Dissolves in water.
