Document Summary
Class notes: solutions = homogeneous mixtures, there are two components: the solute and solvent. Solubility explain why we worry about imfs: miscibility: means infinitely soluble regardless of the percent composition, dispersion means there is a temporary dipole. The only imf that occurs to all nonpolar and polar molecules: dipole dipole is a permanent dipole that occurs in all polar molecules. Be careful, though, as it is not that much smaller: h bonding shows how the h molecule is bond to o, n, or f. these atoms of another molecule. Ion dipole is when an ionic compound dissolves in h2o or the other polar solvent: weakened when heated, qualitative and quantitative. Is something soluble in hexane: polar and hydrogen bonding means that water would not mix with hexane, fatty acids are long nonpolar chains with carboxylic acid ends which is polar.
