PRC Chemist study guide
PRC Chemist · Work through your exam, one topic at a time.
The Chemist Licensure Examination is one of the licensure examinations administered by the Professional Regulation Commission (PRC) of the Republic of the Philippines. Passing it, together with registration, allows a candidate to use the title of Registered Chemist and to hold a Professional Identification Card; the PRC administers the application, examination scheduling, registration, and renewal processes through its official online portals. The PRC Chemist study guide has 6 sections and about 1,888 words.
01General Chemistry - Stoichiometry, Equilibria and Electrochemistry
General Chemistry in the Chemist Licensure Examination covers stoichiometry, gas behaviour, thermochemistry, solution equilibria, periodicity, electrochemistry and nuclear chemistry - the calculation-heavy foundation the other five domains assume. Mole bridge: every quantitative problem passes through moles; convert mass with molar mass, gas volume with 22.414 L/mol at STP, and solution volume with molarity.
310 words, about 2 min02Analytical Chemistry - Classical and Instrumental Quantitative Analysis
Analytical Chemistry tests the full quantitative workflow: sampling, calibration, classical titrimetry and gravimetry, instrumental methods (UV-Vis, AAS, potentiometry, chromatography), and the statistics that decide whether a number is reportable. Primary standards must be high purity, stable, non-hygroscopic, and have a high equivalent weight to reduce weighing error (KHP, Na₂CO₃, K₂Cr₂O₇).
306 words, about 2 min03Organic Chemistry - Nomenclature, Stereochemistry, Mechanisms and Spectra
Organic Chemistry spans IUPAC nomenclature, stereochemistry, reaction mechanisms, functional-group interconversion, and structure elucidation by IR and NMR. Nomenclature priority for the suffix: carboxylic acid ester amide nitrile aldehyde ketone alcohol amine ether halide.
325 words, about 2 min04Physical Chemistry - Thermodynamics, Kinetics and Quantum Foundations
Physical Chemistry covers chemical thermodynamics, phase and solution behaviour, chemical kinetics, electrochemistry, quantum chemistry and spectroscopy from a quantitative angle. First law: ΔU = q + w, with w = −PΔV for expansion work; ΔH = qp at constant pressure.
301 words, about 2 min05Biochemistry - Biomolecules, Enzyme Kinetics and Metabolism
Biochemistry tests the structure and function of biomolecules, enzyme kinetics, bioenergetics and the core metabolic pathways, plus basic molecular biology techniques. Amino acids: the zwitterion dominates near neutral pH; pI is the average of the two pKa values bracketing the neutral form.
314 words, about 2 min06Industrial Chemistry - Unit Operations, Quality Systems and Philippine Regulation
Industrial Chemistry applies unit operations, material and energy balances, process control, quality systems and Philippine regulatory requirements to plant-scale manufacturing. Balances: total mass in = total mass out at steady state; component balances give product splits; energy balances around heat exchangers use Q = m Cp ΔT and LMTD for sizing.
