Inorganic Compounds Inorganic compounds  are typically compounds without carbon atoms. H 2 O, O 2 , and  NaCl are examples of inorganic compounds. Water is the most abundant substance in the body. Its abundance is due partly to its  unique chemical properties created by the influence of its hydrogen bonds. These  properties include the following: Solvency.  Water is an excellent solvent. Ionic substances are soluble in water  (they dissolve) because the poles of the polar water molecules pull them apart,  forming ions. Polar covalent substances are also water-soluble because they  share the same hydrogen bonding as water shares with itself. For this reason,  polar covalent substances are called  hydrophilic  (water loving). Because they  lack charged poles, nonpolar covalent substances do not dissolve in water and are

Unformatted text preview: called hydrophobic (water fearing). • Cohesion. Because water molecules are held together by hydrogen bonds, water molecules have a high degree of cohesion, or the ability to stick together. As a result, water has strong surface tension. This tension, in turn, gives water strong capillary action, allowing water to creep up narrow tubing. These qualities contribute to the movement of water through capillaries. • Stability. The temperature of water is stable. You must add a relatively large amount of energy to warm (and boil) it and remove a large amount of energy to cool (and freeze) it. So, when sweat evaporates from your forehead, a large amount of heat is taken with it and you are cooled....
