What does a pH level of 0-6 indicate?

  1. Acidic pH

  2. Alkaline pH

  3. Neutral pH

  4. Average pH of skin

The correct answer is: Acidic pH

A pH level of 0-6 indicates an acidic pH. This means that the substance or solution has a high concentration of hydrogen ions. A neutral pH is 7, indicating an equal balance of hydrogen ions and hydroxide ions. An alkaline pH is between 8-14, indicating a high concentration of hydroxide ions. An average pH of skin is typically around 5.5, which falls within the acidic range. Therefore, options B, C, and D are incorrect as they do not correctly describe what a pH level of 0-6 indicates.
