Document Summary

Reactions that take place in water, but chemical equilibrium in general. Identify unique properties of water and characteristics that lead to these properties. Apply the rules for solubility to predict formation of precipitates and calculate molar solubility. Predict the direction in which an equilibrium proceeds. 97. 5% of the (cid:449)o(cid:396)ld"s (cid:449)ate(cid:396) is salt (cid:449)ate(cid:396) Allows it to solvolyze ions like sodium. Plays role in folding of proteins because hydrophilic and phobic amino acids interact with water molecules and one another to arrange so minimal unfavourable interactions occur and favourable ones are maximized. Polarity of water determines what molecules (such as ddt) tend to accumulate within an organism, as opposed to those which pass through them. Also determines how molecules bind to receptors, and plays an important role in drug design. Freezes at 0 celsius and freezes at boils at 100 celsius at 1 atm (sea level) Solid phase is less dense than liquid.
