Question

_______ is a measure of the acidity or alkalinity of a solution.
A) Serum
B) Anemia
C) pH
D) Filtration

Accepted Answer

pH measures the acidity or alkalinity of a solution, and it is a scale from 0-14 with 7 being neutral, below 7 being acidic, and above 7 being alkaline/basic. Serum is a component of blood, anemia is a medical condition, and filtration is a process of separating substances. None of these are related to measuring acidity or alkalinity.
