Forensic Chemistry

Forensic Chemistry is the application of chemical science or chemistry in solving or proving the crime in the court of law. Chemical science is being used for the analysis of pieces of evidence found at the scene of a crime. Forensic science in the broadest sense utilizes the principles and methodologies associated with basic sciences for the criminal justice system.
