Question | Answer |
---|---|
Soluble | capable of dissolving in a particle solvent |
solution | a homogenous mixture of two or more substance uniformly dispersed throughout a single phase |
solvent | in a solution the substance in which the solute dissolves |
solute | in a solution the substance that dissolve in the solvent |
suspension | a mixture in which particle of a material are more or less evenly dispersed throughout a liquid or gas |
colloids | a mixture consisting of tiny particles that are intermediate in size between those in solutions and those in suspensions and that are suspended in a liquid, solid, or gas |
Tyndall effect | scatter light |
electrolyte | a substance that dissolves in water to give a solution that conducts an electric current |
nonelectrolyte | a substance that dissolves in water to give a solution that does not conduct an electric current |
solution equilibrium | the physical state in which the opposing processes of dissolution and crystallization of a solute occur at equal rates |
saturated solution | a solution that cannot dissolve anymore solute under the given conditions |
unsaturated solution | a solution that contains less solute than a saturated solution does and that is able to dissolve additional solute |
supersaturated solution | a solution that holds more dissolved solute than is required to reach equilibrium at a given temperature |
solubility | the ability of one substance to dissolve in another at a given temperature and pressure expressed in terms of the amount of solute that will disolve in a given amount of solvent |
hydration | the strong affinity of water molecules for particles of dissolved or suspend substance that causes electrolytic dissociation |
immiscible | describes two or more liquids that do not mix with each other |
miscible | describes two or more liquids that can dissolve onto each other on various proportions |
Henry's law | the law that states that at constant temperature the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas on the surface of the liquid |
effervescence | a bubbling of a liquid caused by the rapid escape of a gas rather than by boiling |
enthalpy of a solution | the amount of energy released or absorbed as heat when a specific amount of solute dissolve in a solvent |
concentration | the amount of s particular substance in a given quantity of a mixture solution or ore |
molarity | a concentration unit of a solution expressed as moles of solute dissolved per liter of solutions |
molality | the concentration of a solution expressed in moles of solute per kilograms of solvent |
