Caution
SAMI (Particle Model of Matter)
Spaces (There are spaces between the particles)
Attraction (Always attracted to each other)
Moving (Always moving)
Identical molecules (Particles are identical)
Paper Chromatography
A technique used to separate and analyze a mixture. This is used to see if a fluid is a pure substance or a solution. If it separates, it is a solution (Substance being tested is solute).
Pure Substance
One element / compound (Ex. Salt, Sugar)
Slurry
A slurry is a mixture of denser solids suspended in liquid. / Usually water
Soluble
The ability of a substance to dissolve in a particular solvent; a substance is able to be dissolved in a particular solvent.
Insoluble
A substance can’t be dissolved in a particular solvent.
(Solubility increases as the temperature of the solvent increases.)
Dissolving
Forming a solution by mixing two or more materials together.
Rate of dissolving: Temperature, size, stirring.
Mechanical Mixture
When different kinds of matter are visible in the mixture, it is called a mechanical mixture. (Can also be called a ‘heterogeneous’ mixture) In a mechanical mixture, the particles are unevenly distributed in groups.
Colloids
Also a cloudy mixture, but particles cannot be easily separated (particles of suspended substance are too small). Two or more substances combined but are not chemically combined.
Suspension
A cloudy mixture in which tiny particles of one substance are held within another
Unsaturated solutions
More solute can be dissolved in a specific amount of solvent, same specific temperature.
Saturated Solution
No more solute will dissolve in a specific amount of solvent at specific temperature.
Solution
One or more solute(s) dissolved in a solvent. (Solute + Solvent = Solution!)
Alloy
A homogeneous mixture of two or more metals, or a metal and a non-metal; solutions of 2 solids (Ex. Steel; iron[metal] + Carbon[ non-metal], Bronze;[copper+tin (both metal), Brass; [copper+zinc (both metal). )
Heterogeneous
Properties of pure substances, in a heterogenous mixture, are not hidden.
Homogeneous
Looks like one set of properties (contains two or more substances)
Mixture
A substance consisting of two or more substances, a combination of pure substances. (Ex. Kool-aid, Trail Mix)
