The Brønsted–Lowry theory is an acid–base reaction theory which was proposed independently by Johannes Nicolaus Brønsted and Thomas Martin Lowry in 1923. This polyatomic ion is called phosphate. These compounds are amphiprotic, meaning that in water they can behave as both a proton donor or a proton acceptor (acid or a base). HCl is a strong acid. Click to see full answer. The conjugate acid of ch3nh2 is ch3nh3+. The fundamental concept of this theory is that when an acid and a base react with each other, the acid forms its conjugate base, and the base forms its conjugate acid by exchange of a proton (the hydrogen cation, or H +). Na+ forms a strong-base hydroxide, and so, it is hardly an acid. ), Galvanic/Voltaic Cells, Calculating Standard Cell Potentials, Cell Diagrams, Work, Gibbs Free Energy, Cell (Redox) Potentials, Appications of the Nernst Equation (e.g., Concentration Cells, Non-Standard Cell Potentials, Calculating Equilibrium Constants and pH), Interesting Applications: Rechargeable Batteries (Cell Phones, Notebooks, Cars), Fuel Cells (Space Shuttle), Photovoltaic Cells (Solar Panels), Electrolysis, Rust, Kinetics vs. Thermodynamics Controlling a Reaction, Method of Initial Rates (To Determine n and k), Arrhenius Equation, Activation Energies, Catalysts, *Thermodynamics and Kinetics of Organic Reactions, *Free Energy of Activation vs Activation Energy, *Names and Structures of Organic Molecules, *Constitutional and Geometric Isomers (cis, Z and trans, E), *Identifying Primary, Secondary, Tertiary, Quaternary Carbons, Hydrogens, Nitrogens, *Alkanes and Substituted Alkanes (Staggered, Eclipsed, Gauche, Anti, Newman Projections), *Cyclohexanes (Chair, Boat, Geometric Isomers), Stereochemistry in Organic Compounds (Chirality, Stereoisomers, R/S, d/l, Fischer Projections).
