Inorganic Chemistry Exam 3
UPDATED Study Guide QUESTIONS
AND CORRECT ANSWERS
- acid, base - CORRECT ANSWERS If a solvent can auto-
ionize, the cation is a/an ____________ and the anion is a/an
________________
protic solvent - CORRECT ANSWERS a solvent that when it
auto-ionizes produces protons (ex. H2O)
aprotic solvent - CORRECT ANSWERS a solvent that has no
acidic protons; a solvent with no O-H or N-H groups
Bronsted theory aqueous solvent - CORRECT ANSWERS any
aolute that donates H+ is an acid. Any solute that accepts H+ is a base
PKion - CORRECT ANSWERS The smaller the ___________
the more dissociation and the stronger the it is
Amphoteric - CORRECT ANSWERS a substance that can act
as both an acid and a base
leveling effect of water - CORRECT ANSWERS any acid
stronger than H3O+, or any base stronger than OH- will react with
water to form H3O+, or OH-, respectively; water acts as a base to
make all strong acids appear equally strong, and it acts as an acid to
make all strong bases appear equally strong
,Use F+ and Cl-. They are stronger acidic species than H+ in water -
CORRECT ANSWERS Due to the leveling effect, how can
we produce extremely strong acids?
F+ and Cl- are - CORRECT ANSWERS super acids
[Cation] , [Anion] - CORRECT ANSWERS For an aprotic
super acid/base system, a species that increases the ______________
is an acid and any species that increases _______________ is a base
stronger - CORRECT ANSWERS A higher Ka indicates a
____________ acid
stronger - CORRECT ANSWERS Small pKa's indicates a
____________ acid
increasing (HI is a stronger base than HF) - CORRECT ANSWERS
Acid strength increases with _____________ bond length
increasing (ex. HF is stronger than CH4) - CORRECT ANSWERS
Acid strength increases with _____________ bond polarity
increases - CORRECT ANSWERS Across table, HA strength
_____________
, increases - CORRECT ANSWERS down table, HA strength
_______________
electronegativity (ex. HOCl is stronger than HOI) - CORRECT
ANSWERS Oxoacids increase acid strength with increased
___________________ of X
oxidation number - CORRECT ANSWERS Oxoacids increase
acid strength with increased ___________________ of X
acidic - CORRECT ANSWERS Metal ions in aqueous
solution are ____________
How are metal ions acidic? - CORRECT ANSWERS When
water complexes with transtion metal ion, it weakens the O-H bond
+2, +3, +4 - CORRECT ANSWERS ______ transition metal
ions are weaker
______ transition metal ions are stronger
______ transition metal ions are much stronger
stronger - CORRECT ANSWERS Higher the charge of the
cation, the _____________ the acid
Be(OH)2 is - CORRECT ANSWERS acidic in H2O
