Introduction to Buffer Solutions

These flashcards cover key concepts related to buffer solutions and their behavior in maintaining pH.

Buffer Solution

A solution that can maintain a stable pH when small amounts of acids or alkalis are added.

Weak Acid

An acid that partially dissociates in a solution, producing H plus ions.

Conjugate Base

The species that remains after an acid donates a proton (H plus).

Equilibrium

A state in a chemical reaction where the reactants and products are produced at the same rate, causing no net change.

Alkali

A substance that can accept protons or donate pairs of valence electrons; usually produces OH- ions in solution.

Dissociation

The process by which a compound breaks apart into its constituent parts, often into ions.

pH

A measure of the acidity or basicity of a solution on a scale of 0 to 14.

Soluble Salt

A salt that can dissolve in water to form a solution, often used in buffer solutions.

Sodium Acetate (NaA)

A soluble salt of acetic acid that can contribute to the buffer capacity when dissolved.

Acid-Base Neutralization

A reaction between an acid and a base that produces water and a salt.
