What is pH?

• A. Measurement of acidity and basicity in solutions
• B. Measurement of hair color
• C. Measurement of temperature
• D. Measurement of moisture

Answer: (A)

pH is a measure of how acidic or basic (alkaline) a solution is. It uses a 0 to 14 scale: numbers below 7 indicate acidity, numbers above 7 indicate basicity, and 7 is neutral. The scale is logarithmic and relates to the concentration of hydrogen ions in the solution—the more hydrogen ions, the more acidic the solution. This concept matters in clinical electrolysis because the pH of solutions and products can affect skin tolerance, chemical reactions, and overall safety during procedures. The other ideas—hair color, temperature, or moisture—do not describe acidity or basicity, so they aren’t pH.
