Explore the Brønsted-Lowry acid-base concept, which defines acids as proton donors and bases as proton acceptors. This theory extends beyond Arrhenius's definition, covering acid-base behavior in various solvents. It includes water's amphoteric behavior, common acids like HCl and H2SO4, bases such as NaOH and NH3, and the formation of conjugate acid-base pairs. Neutralization reactions and the relative strengths of acids and bases are also discussed, highlighting their importance in chemical reactions and industrial applications.

Acids are substances that dissociate in water to yield hydrogen ions (H+) and bases are substances that produce hydroxide ions (OH-) in solution
Acids are defined as proton (H+) donors and bases as proton acceptors, applicable in any solvent system
The Brønsted-Lowry theory allows for a more comprehensive understanding of acid-base behavior in various chemical environments, not just aqueous solutions
Water can function as both an acid and a base, depending on the context of the chemical reaction
Water can donate a proton to a base, transforming into the hydroxide ion (OH-) or accept a proton from an acid, becoming the hydronium ion (H3O+)
The Brønsted-Lowry theory effectively describes the versatile role of water in acid-base chemistry, accommodating its ability to switch between acting as an acid or a base
Examples of Brønsted-Lowry acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), nitric acid (HNO3), and acetic acid (CH3COOH)
Examples of Brønsted-Lowry bases include sodium hydroxide (NaOH), potassium hydroxide (KOH), ammonia (NH3), and sodium bicarbonate (NaHCO3)
The Brønsted-Lowry theory introduces the concept of conjugate acid-base pairs, formed in acid-base reactions
Neutralization is a fundamental reaction in acid-base chemistry where an acid and a base react to form a salt and usually water
