What is a Universal Solvent
It's here many substances can be dissolved in water
How would you speed up the dissolving process of a frozen good?
You could stir it, heat it
"Like dissolves Like" what does this mean in the sense of polar and nonpolar
polar molecules dissolve polar molecule
Nonpolar dissolves nonpolar
A heterogeneous is what?
This type of mixture does not have a fized composition. The amount of each substance in different samples of a heterogenous mixture varies, just as the amount of fruit varies in a spoonfull of fruit salad.
A homogeneous mixture is what?
Looks uniform even when you examine it under a microscope because the individual components of the mixture are to small to be seen.
a mixture in whichparticlesof a material are more of less evenly dispersed throughout a liquid or gas
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.
Mayonnaise is and emulsion, it is a colloidin which liquids that usually do not mix are spread throughout each other. The particles are so small that it may appear to be uniform, but it's not
A homogeneous mixture throughout which two or more substances are uniformly dispersed
In a solution, the substance that dissolves in the solvent
In a solution, the substance in which the solute dissolves
ex: water
2 or more liquids that form a single layer when mixed
Name a way to seperate a miscible liquid
a solid or a liquid mixture of two or more metals
ex: brass, bronze, air
A polar molecule has partially charged positive and negative areas, which are indicated by S+ and S-
example: water
Hydrogen Bond
The intermolecular force occurring when a hydrogen atom that is bonded to a highly electronegative atom of one molecule is attracted to two unshared electrons of another molecule
Describes a molecule in which the centers of positive and negative charges are not seperated
The solubility of a substance is the maximum mass of a solute that can dissolve in 100g of solvent at a certain temperature and standard atmospheric pressure
the amount of a particular substance in a given quantity of a mizure, solution, or ore
Saturated Solutions
A solution that cannot dissolve any more solute under the given conditions
Unsaturated Solutions
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
A solution is _______________ as long as more solute can dissolve in it
Supersaturated Solution
A solution that holds more solute than it normally would at a cooler temperature
