Water and It's Solutions
Question | Answer |
---|---|
CAPILLARITY | the rising of a liquid in a narrow tube |
COLLOID | a mixture that contains particles that are evenly distributed through a dispersing medium and do not settle out over time |
DISSOCIATION | the process by which the charged particles in an ionic solid separate from one another, primarily when going into solution |
HEAT OF SOLUTION | the heat taken in or released in the dissolving process |
HYDROGEN BONDING | a connection between the hydrogen atoms on one molecule and a highly electronegative atom on another molecule, but not full covalent bond |
OSMOSIS | the flow of molecules through a selectively permeable membrane driven by concentration difference |
SATURATED SOLUTION | a solution that holds the maximum amount of solute under the given conditions |
SPECIFIC HEAT | a measure of the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree C |
SUPERSATURATED SOLUTION | a solution containing more solute than the usual maximum, they are unstable |
SURFACE TENSION | the force needed to overcome intermolecular attractions and break through the surface of a liquid or spread the liquid out |
TYNDALL EFFECT | the scattering effect caused when light passes through a colloid |
UNSATURATED SOLUTION | a solution in which the amount of solute dissolved is less that the maximum that could be dissolved |
