Answer:
The flame test is important in these fields as it helps scientists in determining the metal ions present in elements under study from their emission spectrum.
Explanation:
The Flame test is an important test in Chemistry that is based on the fact that metal ions emit certain characteristic spectrum. The element under investigation is made to pass through a hot, non-luminous flame. The resulting spectrum emitted determines the present metal ions. It is important in;
1. Forensics: Forensic is the application of scientific methods in detecting crime. If for example, a food substance is poisoned, the flame test can help in determining the metal ions present in the food and to know if they are indeed poisonous.
2. Astronomy: Scientists observe the stars and the spectra emitted by them to know which elements have the same colors. This also helps them to know how many light years away the stars are.
3. Environmental and Industry issues: Some industries may be fund guilty of releasing substances such as in oil exploration or bad water to the environment. Flame tests would help to determine which metal ions are present in these substances and their potential for and degree of harm.
