What does a pH level of 7 indicate?

Acidic pH
Alkaline pH
Neutral pH
Average pH of skin

The correct answer is: Neutral pH

A pH level of 7 indicates a neutral pH, which means that the substance or solution is neither acidic nor alkaline. It is important to note that a pH level below 7 indicates acidity, and a pH level above 7 indicates alkalinity. Option A is incorrect because it refers to acidic pH, which is below 7 on the pH scale. Option B is incorrect because it refers to alkaline pH, which is above 7 on the pH scale. Option D is incorrect as it is specific to skin pH and not a general pH level. Therefore, the correct answer is C, as it is the only option that correctly identifies the neutral pH level.
