24
Q

Inorganic chemistry

Study These Flashcards
A

The study of substances that do not contain the element carbon, but may contain the element hydrogen

25
Ion
An atom or molecule that Carrie's an electrical charge
26
Ionization
The separation of an atom or molecule into positive and negative ions.
27
lipophilic
Having an affinity for or an attraction to fat and oils ( oil-loving).
28
logarithm
Multiples of 10
29
matter
Any substance that occupies space and has mass(weight)
30
miscible
Liquids that are mutually soluble, meaning that they can be mixed together to form stable solutions
31
molecule
A chemical combination of two or more atoms in definite (fixed) proportions.
32
neutrons
Subatomic particles with no charge.
33
oil-in-water emulsion
Abbreviated O/W emulsion; oil droplets emulsified in water.
34
organic chemistry
The study of substances that contain the element carbon.
35
oxidation
A chemical reaction that combines a substance with oxygen to produce an oxide
36
oxidation-reduction
Also known as redox;a chemical reaction in which the oxidizing agent is reduced (by losing oxygen) and the reducing agent is oxidized (by gaining oxygen).
37
oxidizing agent
Substance that release oxygen.
38
pH
The abbreviation used for potential hydrogen. pH represents the quantity of hydrogen ions.
39
pH scale
A measure of the acidity and alkalinity of a substance; the pH scale has a range of 0 to 14 , with 7 being neutral. A pH below 7 is an acidic solution; a pH above 7 is an alkaline solution
40
physical change
A change in the form or physical properties of a substance without a chemical reaction or the creation of a new substance.
41
Physical mixture
A physical combination of matter in any proportion
42
Physical properties
Characteristics that can be determined without a chemical reaction and that do not cause a chemical change in the substance
43
Protons
Subatomic particles with positive charge
44
Pure substance
A chemical combination of matter in definite (fixed) proportions.
45
Reducing agent
A substance that adds hydrogen to a chemical compound or subtracts oxygen from the compound.
46
Silicones
Special type of oil used in the hair conditioners, water- resistant lubricants for the skin,and nail polish dryers
47
Solute
The substance that is dissolved in a solution
48
Solution
A stable physical mixture of two or more substances
49
Solvent
The substance that dissolves the solute and makes a solution
50
States of matter
The three different physical forms of matter; solid,liquid,and gas
51
Surfactants
A contraction of surface active agents; substances that allow oil and water to mix, or emulsify
52
Suspensions
Unstable physical mixtures of undissolved particles in a liquid.
53
Thioglycolic
A colorless liquid or white crystals with a strong unpleasant odor that is used in permanent waving solution.
54
Volatile alcohols
Alcohols that evaporate easily.
55
Volatile organic compounds
Abbreviated VOCs; compounds that contain carbon (organic) and evaporate very easily (volatile).
56
Water-in-oil emulsion
Abbreviated W/O emulsion; water droplets emulsified in oil.
