Webb21 nov. 2024 · What is 'pH Balanced? pH balance is your body's acid-base balance. Your skin’s natural pH balance is mildly acidic and is usually in the range of 4.7 to 5.5 on the pH level scale - anything below is acidic, and above is alkaline. pH balanced means the manufacturer usually formulates the product to the optimum levels. Common … WebbThe magnitude scale is logarithmic, which means that an increase of 1 magnitude unit represents a tenfold increase in energy. For example, an earthquake with a magnitude of 7 is ten times more powerful than an earthquake with a magnitude of 6. pH of a solution: The pH of a solution is a measure of the acidity or basicity of the solution.
