What are some characteristics of pure water?


Quick Answer

In its pure form, water is a colorless, odorless liquid that has a specific gravity, or density, of 1 gram per milliliter at 39.2 degrees Fahrenheit (4 degrees Celsius). If water is not pure, several of its properties change, including its freezing point, boiling point and conductivity.

Full Answer

Pure water freezes at 32 F (0 C) and boils at 212 F (100 C). The presence of a solute, such as sodium chloride, depresses the freezing point and elevates the boiling point. Similarly, the presence of a solute alters the conductivity of water. Pure water is an insulator, meaning it does not conduct electricity. However, the addition of certain salts increases the conductivity of water, allowing electrical current to flow through.
