How do forensic scientists analyze unknown powders?
Forensic labs are often called in to identify unknown powders, liquids and pills that may be illicit drugs. There are basically two categories of forensic tests used to analyze drugs and other unknown substances: Presumptive tests (such as color tests) give only an indication of which type of substance is present -- but they can't specifically identify the substance. Confirmatory tests (such as gas chromatography/mass spectrometry) are more specific and can determine the precise identity of the substance.

What are two ways you can identify a physical property?

Two gram negative bacilli that produce swarming colonies What biochemical tests would you use to identify the bacilli?
To identify the bacilli, biochemical tests such as oxidase test, catalase test, IMViC tests (Indole, Methyl Red, Voges-Proskauer, Citrate), and sugar fermentation tests can be used. These tests can help differentiate between different species and provide valuable information about the metabolic capabilities of the bacteria.
How could you identify two unknown white crystals such as salt and sugar?
If you can isolate the compound individually first, that's the best thing. Further to this, anion and cation tests will tell you what kind of salt it is. There are also tests to determine simple sugars.
