Forensic chemistry is a branch of science that applies chemical principles to solve crimes. It involves analyzing physical evidence from crime scenes, such as drugs, toxins, and explosives. Forensic chemists use various techniques to identify substances and determine their composition, which can provide crucial information in criminal investigations. The findings from forensic chemistry can be used in legal settings to support or refute evidence presented in court. This field often collaborates with other disciplines, such as forensic biology and toxicology, to create a comprehensive understanding of the evidence and its implications in a case.
