Flashcards in C20 Terms Deck (47):
When there is an unbroken phase
A phase that is a minority in a heterogeneous mixture and that is dispersed throughout the continuous phase
Consist of a solid dispersed in a liquid
If the solid in liquid mixture is more like a liquid than a gel
A heterogeneous mixture that contains two or more immiscible particles
Not able to dissolve into another
Forms when a gas is whipped into a liquid so that it makes a mixture of bubbles within the liquid
Tiny solid particles or liquid drops that are dispersed in a gas
If the particles are between 1nm and 1um
Fluid mixtures whose dispersed particles are larger than 1um in size
When a beam of light shines through a mixture and can be clearly seen
Uniform mixtures of pure substances that consist of a single phase
The substance that is to be dissolved
The substance that does the dissolving
The substance formed when mercury is dissolved in gold
Ions are pulled and wedged from the crystal
A substance is soluble when it can be dissolved by a solvent.
Liquids that can freely mix in any proportion.
The maximum amount of solute that will be dissolved in a given amount of solvent at a given temperature
Solutes that cannot mix in certain solvents
States that the greater the pressure of a gas on a liquid the greater the mass of the gas that will remain dissolved at any given temperature.
No more solute can be dissolved in the solvent at this temperature.
Solutions that contain less solute than their solubility
Has more dissolved solute than a saturated solution should have at a given temperature
How much solute in the solution
percentage by mass
The percent of solute in the solution
An SI base unit
Solution concentration measured in intifada of moles of solute per liter of solution.
A physical property of a solvent that depends on the concentration of the solute particles and not the kind of solute.
The number of degrees the freezing point of a solvent is reduced per mole of dissolved solute particles a colligative property of the solvent.
The number of the boiling point is raised
The diffusion of a fluid through a semipermeable membrane from a region of higher concentration to one of lower concentration.
A thin sheet of material that allows solvent particles to pass through but not solute
The driving force of an osmosis
Water is filtered in a pressurized container
What kinds of substances may form mixtures?
Liquids. Solids. Gasses.
Name and describe the two phases of a heterogenous mixture in which one phase is mixed in anther.
What happens to light when it passes through a colloidal a similar colloidal dispersion?
It is refracted.
What is often visibly different about a suspension compared to a similar colloidal dispersion?
The light is bent and reflected
What gas solutions are not possible?
Liquid an solid
Why is water such an effective solvent?
Because the molecules are electrically charged.
Describe the three steps in the solution process.
The solute is placed in the solvent. Ye solute is hydrated. And the solute is dissociated.
How can an unstable solution become supersaturated without any solute being added or any solvent being removed?
The temperature is cooled.
How is the solubility of a solute related to its concentration in general?
It increases it
When mixing a solution to attain a certain concentration measured in percentage by mass how do you determine the amount of solvent needed?
How does the presence of a solute affect the boiling point of a solvent? The freezing point?
It raises it. It lowers it.
