Which of the following is a chemical property of pure water?
A. Pure water is a colorless liquid.
B. Pure water has a density of about 1 g/cm3.
C. Pure water has an acidity of about 7 on the pH scale.
D. Pure water has a boiling point of 212°F (100°C).

Respuesta :

The answer is C. Pure water has an acidity of about 7

Answer: Option C

Explanation:

The physical properties of water includes its color, phase. Water is colorless liquid and absorbs the wavelength of around 750 nm which appears to be blue in color.

The chemical properties that is associated with the water is its pH value. The pure water has a pH value of 7.

The pH value of 7 on the scale states that the water is neither acidic nor basic. It is neutral. Therefore, the correct answer is option C.
