Chapter 7: Solutions (Amber) Flashcards
What is a colloid?
A mixture that consists 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.
What is emulsion?
A mixture in which two or more immiscible liquids in which one liquid is dispersed in the other.
What is a solution?
Homogenous mixture of two or more substances uniformly dispersed throughout a single phase.
What is a solute?
A substance that dissolves in the solvent.
What is a solvent?
The substance in which the solute dissolves.
What is an alloy?
A solid or liquid mixture of two or more metals.
What is a heterogenous mixture?
A mixture composed of dissimilar components.
What is decanting?
To gradually pour from on container to another
What is immiscible?
Two or more liquids that do not mix with one another
What is the Tyndall effect?
The scattering of light
What is suspension?
When the particles of a material are evenly dispersed throughout a liquid or gas in a mixture.
What is a polar compound?
A compound that has a negative charge in one side and positive on the other.
What is hydrogen bonding?
When a bond occurs between two water molecules. The electrons are pull away from the hydrogen atoms of water by the oxygen atom.
What is a nonpolar compound?
Unable to be dissolved in water without charges on opposite sides.
What is solubility?
The ability of one substance to dissolve in another.
What is concentration?
The quantity of the solute in a given volume of a solution.
What is an unsaturated solution?
Contains less than the maximum amount of solute that will dissolve in the solvent under the same conditions.
What is a saturated solution?
When the dissolved solute is in equilibrium with the undissolved solute.
What is a supersaturated solution?
When a solutions holds more solute than it normally can.
What is molarity?
Moles per liter of a solution
What is insoluble?
When a substance is unable to be dissolved
What does it mean to be soluble?
Able to be dissolved
What does it mean to dilute?
To make a substance thinner or weaker by adding water or another solvent to it.
