-
Precipitation reaction
process in which soluble ionic reactants yield an insoluble solid product that drops out of the solution, thereby removing some of the dissolved ions
-
Acid-base neutralization reaction
process in which an acid reacts with a base to yield water plus an ionic compound called a salt
-
Oxidation-reduction reactions
process in which one or more electrons are transferred between reaction partners
-
Only when a solution contains __ will it produce an electric current.
ions (charged)
-
What are electrolytes
Substances such as NaCl or KBr, which dissolve in water to produce conductiong solutions of ions
-
What are nonelectrolytes?
substance which do not produce ions in aqueous solutions (sucrose/ ethyl alcohol)
-
Strong electrolytes vs. weak electrolytes
- Strong: compounds that dissociate to a large extent into ions when dissolved in water
- Weak: compounds that dissociate to a small extent
-
What are nonelectrolytes?
- H2O
- alcohols
- sucrose and organic compounds
-
Can bare hydrogen react on its own?
- as a bare hydrogen nucleus (a proton) with no electron nearby, H+ is much too reactive to exist by itself.
- They give the hydronium ion, H3O+
-
What names go with the contribution of H ions?
- monoprotic (H+)
- diprotic acid (2 H+)
- triprotic acid (3+)
-
What are oxoacids?
they contain oxygen in addition to hydrogen and another element
-
What is an activity series?
series that ranks the elements in order of their reducing ability in aqueous solutions based on a succession of different reactions
-
What is combustion?
burning of a fuel by oxidation with oxygen in air
-
What is bleaching?
uses redox reactions to decolorize or lighten colored materials
-
What is metallurgy?
the extraction and purfication of metals from their ores
-
What is corrosion?
the deterioration of a metal by oxidation
