Aqueous Solutions

Front 1

electrolyte

Back 1

a substance that produces ions when dissolved in water, thus able to conduct electricity.

Front 2

non electrolyte

Back 2

a substance that does not produce ions when dissolved in water or unable to conduct electricity

Front 3

strong electrolyte: define and give an example

Back 3

ionize completely
1. HCl
2. HNO3
3. NaOH

Front 4

Weak electrolyte: define and give examples

Back 4

ionization is incomplete but some conductivity is observed.
1. H3PO4
2. AgCl

Front 5

non electrolyte

Back 5

Does not conduct electricity in a solution. no dissociation occurs.

Front 6

Acid

Back 6

Any substance that is a proton donor to a base

Front 7

Base

Back 7

Any substance that accepts a proton from an acid

Front 8

Amphiprotic solvent

Back 8

a substance which undergoes autoprotolysis or self dissociates. An example is water.

Front 9

Equilibrium

Back 9

the state in which the concentrations of the reactants and products have no net change over time

Front 10

Equilibrium concentration is based on what factors?

Back 10

1. specific equilibrium
2. starting concentrations
3. temperature
4. pressure
5. reaction specific conditions

Front 11

Equilibrium shift

Back 11

reset in equilibrium process caused by system stress which can be caused by any altering conditions.

Front 12

Le Chatelier's principle

Back 12

If a chemical system at equilibrium experiences a change in concentration, temperature, volume, or total pressure, then the equilibrium shifts to partially counter-act the imposed change.

Front 13

Activity Coefficient

Back 13

is a factor used in thermodynamics to account for deviations from ideal behaviour in a mixture of chemical substances.
