1. Common Names vs. Chemical Formulas:
* Common names: These are everyday names for substances that are often simpler and easier to remember than their chemical formulas. Examples include:
* Water (H₂O)
* Salt (NaCl)
* Baking soda (NaHCO₃)
* Chemical formulas: These are written representations of the elements and their proportions in a compound. They use chemical symbols and subscripts to indicate the number of each atom present.
2. Common Names in Chemistry:
* Some chemicals have well-established common names that are widely used in the chemical industry and research.
* Acetic acid: (CH₃COOH) - the main component of vinegar
* Acetone: (CH₃COCH₃) - a solvent used in nail polish remover
* Toluene: (C₇H₈) - a solvent used in paints and adhesives
3. IUPAC Nomenclature:
* The International Union of Pure and Applied Chemistry (IUPAC) has a system for naming chemicals based on their structure. This system provides a unique and unambiguous name for each compound, unlike common names which can sometimes be ambiguous.
