Notes 2.1 - What is the pH scale?

Vocabulary flashcards covering the definition and components of the pH scale, acids, bases, and neutral solutions from Notes 2.1.

pH scale

A logarithmic scale ($0-14$) that determines whether a chemical is an acid ($0-6\,\text{pH}$) or a base ($8-14\,\text{pH}$).

Acid

Any chemical with a high concentration of $H^+$ ions and a pH ranging from $0$ to $6$, where stronger acids have lower pH values.

Base

Any chemical with a high concentration of $OH^-$ ions and a pH ranging from $8$ to $14$.

Neutral pH

The state of any chemical that has a pH value of $7$.
