Term
the arrhenius definition only works well for what kind of solutions
Definition
aqueous
Term
what happens to acids in water
Definition
liberate hydrogen ions
Term
what do bases do in water
Definition
produce hydroxide (OH)
Term
hydronium ion
Definition
H3O+
Term
When does a neutralization reaction occur?
Definition
when H+ and OH- are in excess, and therefore create water
Term
Base that doesn't process OH-
Definition
ammonium
Term
why are aqueous ammonium solutions basic?
Definition
NH3 + H20 = NH4 + OH- (note the production of hydroxide)
Term
what is the Bronsted-Lowry Definition
Definition
acids give off hydrogen ion donor, bases are hydrogen ion acceptors
Term
what happens during an acid base reaction?
Definition
proton and hydrogen ion transfer
Term
bases are often what charge?
Definition
negative or neutral
Term
what charge are acids?
Definition
positive or neutral
Term
conjugate acid base pairs differ by
Definition
presence of H+
Term
in the reaction: HCL + H20 = H3O+ + CL-what are the conjugate acid-base pairs?
Definition
acid-base pairs: HCL/CL- and H2O/H3O+ conjugate acids: HCL and H3O conjugate bases: CL- and H2O
Term
what does it mean to be strong acid or base?
Definition
they dissociate completely in solution (nothing to do with concentration)
Term
the stronger the acid the (blank) the base
Definition
weaker
Term
When H3O is greater than 1 x 10^-7 it is an
Definition
acidic solution
Term
when OH- is greater than 1 x 10^-7 M it is a
Definition
basic solution

solid oxides, hydroxides, or carbonates/bicarbonates
Term
in a typical acid reaction the H+ reacts with
Definition
the anion of the other reagent
Term
what type of reactions are acid reactions?
Definition
double displacement
Term
what is the intermediate compound formed during an acid reaction?
Definition
cabonic acid, which decomposes into water and CO2
Term
another type of acid reaction

Definition
redox
Term
bases generally feel
Definition
soapy or slippery
Term
bases react with fats and oils to form
Definition
smaller molecules
Term
salts
Definition
ionic compounds that have an anion from an acid, and a cation from a base
Term
water is a (blank) bonded part of a molecule
Definition
non-covalently
Term
is water easy or difficult to remove from a molecule
Definition
difficult
