Q

Suspension

A

A mixture in which particles of a material are more or less evenly dispersed throughout a liquid or gas

11
Q

Tyndall effect

A

The visible path of light produced by the scattering action (Tyndall effect) of the particles in a colloidal solution on a beam of light passed through it

12
Q

polar compound

A

A compound made up of molecules joined by assymetrical polar bonds

13
Q

hydrogen bonding

A

The intermolecular force occurring when a hydrogen atom that is bonded to a highly electronegative atom of one molecule is attracted to two unshared electrons of another molecule

14
Q

nonpolar compound

A

A compound comprised of molecules linked through chemical bonds arranged in such a way that the distribution of charges are symmetrical

15
Q

solubility

A

The ability of one substance to dissolve in another at a given temperature and pressure; expressed in terms of the maximum amount of solute that will dissolve in a given amount of solvent

saturated solution

A

A solution that cannot dissolve any more solute under the given conditions

19
Q

supersaturated solution

A

To cause (a chemical solution) to be more highly concentrated than is normally possible under given conditions of temperature and pressure
