1. Water Concept Map

2. Liquid water forms hydrogen bonds, is a solvent & forms ions, allowing a wide range of biochemical reactions
WATER
Special Properties of Water
Water can dissociate into hydrogen (H+) & hydroxide (OH-)ions
Polarity
Hydrogen Bonding 1
Acid:
more H+ ions
Base:
more OH- ions
Hydrogen bonds don’t break too easily: it takes a lot of cooling to cause water to freeze, and a lot of heat to make it evaporate.
Cohesion: water sticks to other water
Universal Solvent: Water is polar & dissolves other polar solutes 2
Adhesion: water sticks to other things 1
High Specific Heat
Capillary Action 2
High Heat of Evaporation 3
High Heat of Fusion 4
Density: expansion on freezing (makes ice float; fish don’t freeze)
