Because the substance could potentially be extremely toxic or harmful. You must never use an unknown substance in experiments without identifying it first, many tests can be undertaken to determine the cation and anion. These tests include the flame test, solubility tests, precipitate reaction tests and conductivity tests. These do vary depending on the unknown substance.

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.
