Pure water is an example of which of the following?

Correct answer

A neutral substance (pH 7)

A A strong acid
B A neutral substance (pH 7)
C A strong alkali
D An emulsion

Why this is the answer

Pure water is a neutral substance with a pH of 7 — neither acidic nor alkaline. It serves as the reference point for the pH scale. In cosmetology, water is also the most common solvent, used to dilute and mix many products. (Tap water may vary slightly due to dissolved minerals, but pure water is defined as neutral.) Recognizing pure water as the pH-7 neutral standard is a basic chemistry fact within the scientific-concepts content of the licensing exam.
