WebApr 5, 2024 · There are two important reasons why chlorides are preferred for the flame test. Let’s understand the given reasons: Metal chlorides are found to be more volatile than other metal salts. When a compound is volatile it quickly evaporates from the solid to gaseous form. Metal chlorides evaporate under the flame and thus give a bright colour.
