- Physical Chemistry: Focus on the physical principles underlying chemical systems, including thermodynamics and kinetics.
- Analytical Chemistry: Techniques and methods used to analyze substances, both qualitative and quantitative.
- Biochemistry: Intersection of biology and chemistry, studying chemical processes within and related to living organisms.
General Concepts:
- Atoms and Molecules: Basic units of matter; atoms combine to form molecules.
- Chemical Reactions: Processes where reactants are transformed into products, involving bond breaking and formation.
- Stoichiometry: Quantitative relationship between reactants and products in a chemical reaction.
- Chemical Equilibrium: State where the rate of forward reaction equals the rate of reverse reaction.
- Acids and Bases: Substances that donate (acids) or accept (bases) protons, following theories like Arrhenius, Bronsted-Lowry, and Lewis.
Laboratory Skills:
- Techniques: Filtration, distillation, titration, chromatography, spectroscopy.
- Safety Measures: Use of personal protective equipment (PPE), understanding Material Safety Data Sheets (MSDS), and proper waste disposal.
Analytical Techniques:
- Chromatography: Separation of mixtures based on differences in affinity between stationary and mobile phases.
- Spectroscopy: Study of interactions between matter and electromagnetic radiation; includes UV-Vis, IR, NMR.
- Mass Spectrometry: Technique for analyzing the mass-to-charge ratio of ions to identify compounds.
Important Laws and Theories:
- Law of Conservation of Mass: Mass is neither created nor destroyed in a chemical reaction.
- Dalton's Atomic Theory: Elements consist of indivisible atoms and compounds are combinations of different atoms.
- Le Chatelier's Principle: If a dynamic equilibrium is disturbed, the system shifts to counteract the disturbance.
Key Topics in Biochemistry:
- Enzymes: Biological catalysts that speed up biochemical reactions.
- Metabolism: Chemical reactions that take place within a cell, including catabolism (breaking down molecules) and anabolism (building up molecules).
- Nucleic Acids: DNA and RNA structures and functions; the basis for genetic information.
Environmental Chemistry:
- Pollutants: Study of chemical substances that harm the environment.
- Green Chemistry: Designing chemical products and processes that reduce or eliminate the use and generation of hazardous substances.
Career Opportunities:
- Research Scientist: Conduct experiments and research in industry or academia.
- Quality Control Analyst: Ensure products meet regulatory and safety standards.
- Chemical Engineer: Apply chemical principles to design processes and equipment.
- Pharmaceuticals: Work in drug development, testing, and marketing.
Skills Developed:
- Analytical thinking and problem-solving.
- Laboratory proficiency with hands-on experiments.
- Data interpretation and statistical analysis.
- Understanding of scientific literature and communication.
