What does pH stand for?

pH stands for "Potential Hydrogen." It is a scale used to specify the acidity or basicity of a solution. The term "potential" indicates the capability of hydrogen ions (H⁺) in a solution to either donate or accept protons, affecting the solution's overall acidity or alkalinity. The pH scale typically ranges from 0 to 14, with lower values representing more acidic solutions (higher concentration of hydrogen ions) and values above 7 representing basic or alkaline solutions (lower concentration of hydrogen ions). The concept of pH is crucial for estheticians as it influences the effectiveness and safety of skincare products and treatments.

In this context, understanding pH helps professionals assess the suitability of products for various skin types and conditions, ultimately guiding effective skincare regimens. The other options do not accurately reflect the scientific term associated with the pH scale: "Power of Hydrogen," "Potency of Hydrogen," and "Pressure of Hydrogen" do not capture the essential aspect of the "potential" in relation to hydrogen ions in a solution.
