chem mixtures and solvation

heterogeneous mixture

* diff particles do not blend smoothly
* not uniformly mixed
* diff ratios of substances taken w different samples
* (italian salad dressing)

suspension

* type of ==heterogeneous== mixture


* particles will settle out if left undisturbed

**(large particles, able to filter)**
* ex: sand and water

colloid

* type of ==heterogeneous== mixture
* particles WILL NOT settle out if left alone **(intermediate particles, unable to filter)**
* illusion of being a solution- looks like a solution to the eye, but acc isn’t
* ex: milk

tyndall effect

the scattering of light by the dispersed particles in a colloid

homogeneous mixture

diff particles blend smoothly and r not visible to thruout the mixture

(uniformly mixed, all samples would have the same ratio of particles)

solution

a ==homogeneous mixture== where one substance is dissolved in another

* can b a solid, liquid, or gas
* **solution has the same state of matter as the solvent**

solute

* the substance that is dissolved
* makes up the minority of a solution

solvent

* the dissolving medium (the substance that does the dissolving)
* H20= universal solvent

soluble

describes a substance that CAN B DISSOLVED in a given solvent (water soluble)

miscible

two liquids that r soluble in each other

insoluble

a substance that CAN’T b dissolved in a given solvent

immiscible

two liquids that can b missed together ==but separate shortly after==

(oil and water)

is dissolving a reaction?

NO. cuz no new substance is formed, and the substances can b separated by a physical process

solvation/process of dissolving/dissolution

solute particles ripped away by solvent particles ya yk

factors that effect rate of solvation

* agitation (stirring)
* temp
* surface area
