How to fill out identification of unknown solids?

1. Gather the necessary equipment for identification, including a magnifying glass, balance, and various testing reagents.
2. Carefully observe the physical characteristics of the unknown solid, such as color, texture, and shape. Take note of any noticeable odor as well.
3. Conduct a density test by weighing the solid and recording its mass. Then, measure the volume by immersing the solid in water and recording the displacement. Divide the mass by the volume to determine the density.
4. Perform a solubility test by adding the solid to different solvents and noting whether it dissolves or remains insoluble.
5. Use a magnifying glass or microscope to examine the unknown solid's crystal structure, if visible. This can provide insight into its composition.
6. Conduct a flame test by heating a small portion of the solid over a flame and observing the color of the flame. Different elements exhibit characteristic flame colors, which can assist in identification.
7. Perform additional tests, such as pH testing, conductivity testing, or reaction tests with acids or bases, to further narrow down the possible compositions of the unknown solid.
8. Compare the results of the tests to known substances or reference materials to identify the unknown solid.
