Interpretation:
The unique properties of water are to be provided and their importance is to be determined.
Concept Introduction:
Water is a common liquid that is present on the Earth.
It is also known as universal solvent. It can dissolve a wide range of organic and inorganic solutes.
Water is vital for the existence of all living animals. Without water, no life form can exist, it constitutes an important part of rivers, lakes, streams, clouds, snow and ice.
Water is truly an unusual molecule such that being a low molar mass compound, it exists as a liquid at room temperature and has an anonymously high boiling point.
Ice floats on water because it has a lower density than water.
The temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere is called boiling point.
A hydrogen bonding is a partially electrostatic force of attraction between a hydrogen atom which is bound to more electronegative atom such as nitrogen, oxygen or fluorine and another atom bearing a lone pair of electrons.
A molecular formula consists of the

- In what ways is water unique? What about the water molecule causes the unique properties of water?arrow_forwardRefer to Figure 11.12 to answer these questions: (a) You heat some water to 60 C in a lightweight plastic bottle and seal the top very tightly so gas cannot enter or leave the carton. What happens when the water cools? (b) If you put a few drops of liquid diethyl ether on your hand, does it evaporate completely or remain a liquid? Figure 11.12 Vapor pressure curves for diethyl ether [(C2H3)2O], ethanol (C2H5OH), and water. Each curve represents conditions of T and P of which the two phases, liquid and vapor, are in equilibrium. These compounds exist as liquids for temperatures and pressures to the left of the curve and as gases under conditions to the right of the curve. (See Appendix G for vapor pressures for water of various temperatures.)arrow_forward
