16
Q

Paper Chromatography

A

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).

17
Q

Pure Substance

A

One element / compound (Ex. Salt, Sugar)

18
Q

Slurry

A

A slurry is a mixture of denser solids suspended in liquid. / Usually water

19
Q

Soluble

A

The ability of a substance to dissolve in a particular solvent; a substance is able to be dissolved in a particular solvent.

20
Q

Insoluble

A

A substance can’t be dissolved in a particular solvent.
(Solubility increases as the temperature of the solvent increases.)

21
Q

Dissolving

A

Forming a solution by mixing two or more materials together.
Rate of dissolving: Temperature, size, stirring.

22
Q

Mechanical Mixture

A

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.

23
Q

Colloids

A

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.

24
Q

Suspension

A

A cloudy mixture in which tiny particles of one substance are held within another

25
Q

Unsaturated solutions

A

More solute can be dissolved in a specific amount of solvent, same specific temperature.

26
Q

Saturated Solution

A

No more solute will dissolve in a specific amount of solvent at specific temperature.

27
Q

Solution

A

One or more solute(s) dissolved in a solvent. (Solute + Solvent = Solution!)

28
Q

Alloy

A

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). )

29
Q

Heterogeneous

A

Properties of pure substances, in a heterogenous mixture, are not hidden.

30
Q

Homogeneous

A

Looks like one set of properties (contains two or more substances)

31
Q

Mixture

A

A substance consisting of two or more substances, a combination of pure substances. (Ex. Kool-aid, Trail Mix)
