chem U9


intramolecular forces the attraction between atoms within a molecule
intermolecular forces the attraction between molecules
hydrogen bonding the attraction of a bonded hydrogen atom to an unbonded electron pair on another molecule
surface tension the resistance of a liquid to an increase in surface area
cohesive forces the forces holding the liquid together to present the minimum surface area
in water,is the solid phase more or less dense than the liquid phase? solid phase is LESS dense
capillary action the spontaneous rising of liquid in a narrow tube due to cohesion and adhesion
adhesion 2 different things sticking to each other
solute the thing being dissolved
solvent the one doing the dissolving
do solutes dissolve in solvents with similar or opposite polarity? similar
dissocation/ionization ionic compound splitting apart
hydration (solvation)
why might you need more solvent than solute? the solvent may have slight +/- charges whereas the solute is held together by complete +/- charges
hard water water that has Ca2+, Mg2+, Fe2+ (notice these all are higher than a charge of 1)
soft water water that has Na+ or K+ ions in it (notice how these only have a charge of 1+)
where does the solvent start dissolving in terms of the location of the solute? the edges of the solute
