Name: Score:108 Multiple choice questions
Term 1 of 108
Inhibitor
Materials that produce hydroxide ions when dissolved in water.
Most caustic materials exist in a solid state.
Material that is added to product that easily polymerizes in order to control or prevent an
undesired reaction
Amount of energy that must be added to an atomic or molecular system to begin reaction
Can be the most dangerous because of the potential for fire or explosion
removing heat from an exothermic reaction can slow and eventually stop reaction
Term 2 of 108
Ionically bonded compounds
Solid, limited to no vapor, no flash point, no LEL, will not polymerize, may form basic
solution, may be air or water reactive, no seen on IR or PID
All are flammable or combustible, depending on flash point
All are toxic at some degree
All are insoluble in water and float on the surface
Can be the most dangerous because of the potential for fire or explosion
Removing heat from an Exothermic reaction can slow and eventually stop reaction
Reacts with water, can be mild to severe, especially with alkali metals
A water reactive material is defined by the gases it gives off; toxic, corrosive, flammable
,Term 3 of 108
Degrees of Solubility
Negligible- less than 0.1%
Slight- 0.1-1.0%
Moderate- 1-10%
Appreciable- greater than 10%
Complete- soluble at all proportions
Heat generally increases solubility for solids to liquid
Solid, limited to no vapor, no flash point, no LEL, will not polymerize, may form basic
solution, may be air or water reactive, no seen on IR or PID
Can affect the behavior, chemical and physical properties of materials
i.e. Temperature, relative humidity
Definition 4 of 108
The risk of flammable atmosphere or container failure must always be considered near and
around acid spills
Acid strength
Reactive material
Acid spills
Ph scale
Term 5 of 108
Condensation
Substance capable of or tending to react chemically with other substances
Process of going from the gaseous to the liquid state
Referring to the by weight or volume of an acid or a base to water
Expressed in percentages, molarity or normality
Expressed in percentage of the total volume in water and molarity
,Term 6 of 108
Solvent
Substance capable of or tending to react chemically with other substances
A substance in which other substances are dissolved, often a liquid
Degree to which a solid, liquid or gas dissolves in a solvent
Substance that contains two or more materials not chemically bonded
Definition 7 of 108
Materials that are capable of being mixed, mixes 100%
Miscible
Inorganic Compounds
Solution
Mixture
Definition 8 of 108
Also known as the explosive or combustible range
Flash point
Miscibility
Vapor pressure
Flammable range
, Term 9 of 108
Solute
A substance that influences the rate of chemical reaction between or among other
substances
Substance capable of or tending to react chemically with other substances
Substance dissolved in another substance
Degree to which a solid, liquid or gas dissolves in a solvent
Term 10 of 108
Hydrocarbon examples
Methane, pentane, propane, octane
Compounds consist solely of hydrogen and carbon
Any substance in which two or more chemical elements (usually other than carbon) are
combined, nearly always in definite proportions.
many inorganic compounds are consider ionic compounds that are joined by ionic bonding
Alkanes, alkenes, alkynes, aromatics
Term 11 of 108
Tissue damage (Bases)
Chemically converting fat into alcohols, salts and soaps. Bases break down proteins.
The temperature above which the decomposition of an unstable substance continues
unimpeded, regardless of the ambient or external temperature.
The maximum safe temperature at which a product can be stored. this temperature is well
below the sadt.
The lowest temperature at which a substance will ignite in air without an ignition source
