Question | Answer |
---|---|
continuous phase | an unbroken phase that makes up most of a heterogeneous mixture in which other phases are dispersed |
dispersed phase | a phase that is a minority in a heterogenous mixture and that is dispersed or suspended throughout the continuous phase |
gel | a two-phase heterogeneous mixture in which dispersed solid particles form an open network throughout a liquid continuous phase, giving some rigidity to the mixture |
foam | a heterogeneous mixture in which a gaseous phase consisting of tiny bubbles is dispersed in a liquid or solid |
aerosol | a heterogeneous mixture consistin of tiny solid particles or liquid drops in a gas |
solution | a homogeneous mixture of two or more pure substances |
solute | the substance dissolved in the solvent in a solution; the minority component in a solution |
solvent | the substance that does the dissolving in a solution; the majority component of a solution |
Tyndall effect | the scattering of light off dispersed or suspended particles in a heterogeneous fluid mixture |
soluble | anle to dissolve in a certain solvent |
miscible | soluble in another liquid;used of liquids |
solubility | the maximum amount of solute that can be dissolve in a given amount of a prticular solvent at a specified temerature |
insoluble | unable to dissolve in a certain solvent |
Henry's law | law stating that the greater the pressure of a gas on a liquid, the greater the mass of the gas that can dissolve in the liquid at a given temperature |
saturated | discribes a solution in which the solure's concentration is at its solubility limit. |
insaturated | describes a solution in which the solute concentration is below its solubility limit. |
supersaturated | describes a solution in which the solure concentraion exceeds its nowmal solubility limit under existing conditions, a highly unstable condidtion that can result in rapid precipitation of the solute |
