On the pH scale, which range indicates an acidic product?

7.1-14
6.0-8.0
0-6.9
5.0-9.0

The correct answer is: 0-6.9

The range that indicates an acidic product on the pH scale is from 0 to 6.9. pH measures the concentration of hydrogen ions in a solution; the lower the pH value, the more acidic the substance is. Pure water has a neutral pH of 7.0, and any substance with a pH below 7.0 is classified as acidic. This understanding is critical in the field of esthetics, as many facial products and treatments rely on the pH level for their effectiveness. In contrast, values above 7.0 indicate a basic or alkaline product. Therefore, knowing the acidic range is particularly important when selecting products for skin care treatments, as products with a proper pH can help balance the skin's natural barrier and function effectively in treating various skin concerns.
