Question | Answer |
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 |
cohesion | |
adhesion | 2 different things sticking to each other |
solubility | |
solute | the thing being dissolved |
solvent | the one doing the dissolving |
do solutes dissolve in solvents with similar or opposite polarity? | similar |
why? | |
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 |
