Which of the Following is a Chemical Property of Water

Question

Which of the following is a chemical property of water? A) Water vapor has no definite volume. B) Water has a density of 1000 kg/m³. C) Water reacts violently with potassium. D) Ice floats in water.

Accepted Answer

Chemical properties relate to the ability of a substance to undergo chemical reactions and form new substances. Water reacting with potassium is a chemical reaction, and therefore a chemical property of water. Choices A and B are physical properties, whereas choice D is a consequence of a physical property (the fact that ice is less dense than liquid water).
