Solutions Flashcards
solvent
dissolving medium in solution
solute
substance which is dissolved in solution
substance of lesser quantity in solution
solute
size of particles in solution
small enough to travel through filter paper
suspension
mixture with particles that are too large to settle out unless it is constantly stirred or agitated
size of particles of suspension
large enough to be separated by filter paper
separation of particles in suspension
separated by filtration
colloid
mixture with particles that are intermediate in size between those in solutions and suspensions
size of particles in colloid
small enough to travel through filter paper
dispersed phase
phase that is composed of colloidal particles that are distributed through another phase
dispersing medium
phase in which the colloidal particles of the dispersed phase are distributed
emulsion
type of colloid composed of 2 or more liquids that are normally immiscible
held together by emulsifying agent
tyndall effect
scattering of light beams by colloidal particles dispersed in transparent medium
used to differentiate between solutions and colloids
Brownian motion
random motion of particles suspended in fluid
results from collision with fast-moving molecules in fluid
electrolyte
solution that contains ions
conductive of electricity
processes which form electrolytes
ionization
dissociation
nonelectrolyte
solution that does not contain ions
not conductive of electricity
methods to increase rate of dissolution
increasing surface area of solute (crushing a solid solute)
agitating solution (stirring or shaking)
heating solvent
