pH Assignment Vocabulary

Vocabulary flashcards covering key concepts from the pH assignment, including pH scale definitions, acidity, alkalinity, ion concentrations, and physiological blood pH levels.

Acidosis

A condition caused by an abnormally low body fluid pH, with symptoms including headache, confusion, tiredness, shortness of breath, and in severe cases, coma or death.

Alkalosis

A condition caused by an abnormally high body fluid pH, with symptoms including confusion, lightheadedness, muscle spasms or twitching, and numbness or tingling.

pH

A measurement of hydrogen ion ($H^+$) concentration that indicates how acidic or basic a solution is.

Neutral pH

A pH value of $7$, which indicates that a solution is neither acidic nor basic.

Acid

A substance or solution with a pH value below $7$ (ranging from $0$ to $6$).

Base

A substance or solution with a pH value above $7$ (ranging from $8$ to $14$), also referred to as alkaline.

Strongest Acid

The pH value of $0$ on the pH scale, representing the highest concentration of hydrogen ions ($H^+$).

Strongest Base

The pH value of $14$ on the pH scale, representing the lowest concentration of hydrogen ions ($H^+$).

10-fold Difference (pH Scale)

The magnitude change in hydrogen ion ($H^+$) concentration and acid or base strength corresponding to a difference of $1$ unit on the pH scale.

Normal Blood pH

The target pH level for blood, which has a set point of $7.4$ and a normal range of $7.35$ to $7.45$.
