MCAT General Chemistry | Latest Update | 2024/2025 | Already Passed What is the role of the conjugate base in an acid-base reaction, and how does it influence the reaction equilibrium? The conjugate base is formed when an acid donates a proton. It influences the reaction equilibrium by interacting with the acid, shifting the equilibrium based on the relative strengths of the acid and its conjugate base. How does the presence of a common ion affect the solubility of a salt in a solu...

MCAT General Chemistry (Princeton Review) Questions and Answers | Latest Update | 2024/2025 | Already Passed What is the role of a Lewis acid and a Lewis base in a chemical reaction? A Lewis acid is an electron pair acceptor, while a Lewis base is an electron pair donor. They interact to form a coordinate covalent bond where the base donates an electron pair to the acid. How does the concept of bond enthalpy relate to the strength of a chemical bond? Bond enthalpy (or bond dissoci...

Henderson-Hasselbach Equation - pH = pKa + log ([A-] / [HA]) FMOC Chemical Synthesis - Used in synthesis of a growing amino acid chain to a polystyrene bead. FMOC is used as a protecting group on the N-terminus. Salting Out (Purification) - Changes soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solution. Size-Exclusion Chromatography - Separates sample based on size with smaller molecules eluting later. Ion-Exchange...
