Chemistry Lecture Notes on Acid-Base Concepts

Flashcards covering key vocabulary and concepts from acid-base chemistry related to equilibrium, pH, and reactions.

Equilibrium Expression (K)

Represents the ratio of concentrations of products to reactants at equilibrium.

Ka

Acid dissociation constant, quantifies the strength of an acid in solution.

Kb

Base dissociation constant, quantifies the strength of a base in solution.

pH

Measure of acidity or alkalinity of a solution, calculated as -log[H+].

Neutralization

Reaction where an acid and a base react to form water and a salt.

Strong Acid

Acid that completely dissociates in solution, like HCl.

Weak Acid

Acid that does not completely dissociate in solution, like acetic acid (CH3COOH).

Limiting Reactant

The substance that is completely consumed in a reaction, determining the amount of product formed.

pOH

Measure of the hydroxide ion concentration, calculated as -log[OH-].

Inversely Related

Referring to how [H+] and [OH-] concentrations change in relation to one another; as one increases, the other decreases.
