The pH of the adult female vagina is normally:
A
highly acidic, below 2.0
B
acidic, around 4.5
C
alkaline, around 8.5
D
neutral, around 7.0
Verified step by step guidance1
Understand the concept of pH: pH is a scale used to measure the acidity or alkalinity of a solution, ranging from 0 (highly acidic) to 14 (highly alkaline), with 7 being neutral.
Recognize the physiological importance of vaginal pH: The vaginal environment is naturally acidic to help prevent infections by inhibiting the growth of harmful bacteria and fungi.
Learn the typical pH range for the adult female vagina: The normal vaginal pH is slightly acidic, typically around 4.5, which is maintained by the presence of lactic acid produced by Lactobacillus bacteria.
Compare the options provided: Evaluate each option based on the known physiological pH range of the vagina. Highly acidic (below 2.0) is too extreme, alkaline (around 8.5) is incorrect, and neutral (around 7.0) does not align with the normal acidic environment.
Conclude that the correct answer is 'acidic, around 4.5,' as this matches the physiological pH range of the adult female vagina.
