What is the range of the pH scale?

The pH scale is a widely used measurement that quantifies the acidity or alkalinity of a solution. The scale ranges from 0 to 14, where a pH of 7 is considered neutral. Values less than 7 indicate acidic solutions, while values greater than 7 indicate alkaline (or basic) solutions. This range is crucial in many fields, including beauty and personal care, where the pH level can affect the stability and effectiveness of products used in manicuring and skincare.

Understanding this scale is vital for professionals in manicuring, as it helps them select appropriate products for nails and skin. A product that is too acidic or too alkaline can lead to irritation or damage. Therefore, the complete range of 0-14 is essential knowledge for ensuring proper care and safety in nail and skin treatments.
