pH and pOH Lecture

Flashcards covering key concepts from the lecture notes on pH, pOH, acids, and bases.

pH

Minus log of the concentration of H₃O⁺ in solution.

pOH

Minus log of the concentration of OH⁻ in solution.

Acidic

A solution with a pH less than 7.

Neutral

A solution with a pH of approximately 7.

Basic

A solution with a pH greater than 7.

Strong Acids

Acids that dissociate completely in water such as hydrochloric, hydrobromic, hydroiodic, sulfuric, nitric, and perchloric acid.

Strong Bases

Bases that dissociate completely in water, typically alkali metal hydroxides and some alkaline earth metals.

Conjugate Acid

The species formed when a base gains a hydrogen ion.

Conjugate Base

The species formed when an acid donates a hydrogen ion.

Tug of War Analogy

A way to compare the strength of acids and bases: the stronger one 'wins' in neutralization reactions.

Measurement Error

The concept that all measurements have some level of error, regardless of the device used.
