Equal concentrations of H and OH- ions. 22 Properties of Water The Water Molecule Water molecules H 2 O are polar because of an uneven distribution of electrons creating a slight negative charge in the oxygen atom and a slight positive charge in each hydrogen atom. It also explains what acidic solutions and basic solutions are.
Section 22 Properties of Waterpages 4043 This section describes the makeup of water molecules. The Water Moleculepages 4041 1. A molecule in which the charges are unevenly distributed is said to be polar because the molecule is a bit like a magnet with two poles.
High specific heat cohesion adhesion FIGURE 23 The waters surface left dyed red is curved down because water has greater adhesion than cohesion. Some of the most important biological fluids contain water. Properties of Water 1.
The molecule has two poles at which the it is colder than other regions of the molecule. Polar molecules have slightly charged regions. Explain why water is a polar molecule.
