The tendency of water molecules to gets as close together as possible. "Bead up" caused by H bonds
breaks H bonds of surface tension(ex: detergent/ soap)
dissolving medium--> water is the universal solvent
compounds that conduct electricity in aqueous solutions-mostly ionic
compounds that do not dissolve electricity in an aqueous solution
hydrates (aka water of hydraton)
molecules that contain water as part of their crystal structure. ex: CuSO4 (dot) 5H2O= Copper (II) sulfate pentahydrate. Forces holding water molecules in hydrates are not very strong- sometimes they efflorece.
lose water of hydration when hydrate has a vapor pressure higher than H2O vapor pressure-the loss of water (or a solvent) of crystallization from a hydrated or solvated salt to the atmosphere on exposure to air
hydrated salts which remove moisture from the air. (Often used as desiccants or drying accents)-little packaging in shoes
compounds that absorb so much water from the air that they become wet. These will actually become solutions
the amount of a substance that dissolves in a given quantity of a solvent at a given temp. to produce a saturated solution
contains the maximum amount of solute for a given amount of solvent at a constant temp.
contains less solute than a saturated solution
able to be dissolved
a solution that contains more solute than it should theoretically hold at a given temp.
measure of the amount of solute that is dissolved in a given quantity of solvent
mixture in which one substance is dispersed evenly throughout the other (ex: milk, butter, cream...)
light dispersion due to the colloidal particles
a mixture of 2 or more immiscible (un-blendable) liquids; (ex: vinegarettes)
scattering of a light beam as it passes through a colloid
the idea that the atoms that make up matter are in constant motion
a mixture in which fine particles are suspended in a fluid where they are supported by buoyancy
