Document Summary
Bisc 100 atoms and properties of water part 2. Moderation of temperature by water: water absorbs heat from warmer air and releases stored heat to cooler air, water can absorb or release a large amount of heat with only a slight change in its own temperature. Water: the solvent of life: water is a versatile solvent due to its polarity, when an ionic compound is dissolved in water, each ion is surrounded by a sphere of water molecules called a hydration shell. Water: the solvent of life: water can also dissolve compounds made of nonionic polar molecules, even large polar molecules such as proteins can dissolve in water if they have ionic and polar regions. Acidic and basic: water is in a state of dynamic equilibrium in which water molecules dissociate at the same rate at which they are being reformed.
