ACID and BASE Review
Card Set Information
ACID and BASE Review
Identify whether a chemical is an acid or a base by its formula or name.
: H - non metal
Acid names have 'acid' on it
: metal - OH
Base names have hydroxide or amine
How do you name bases?
ex. sodium hydroxide
How do you name acid with one type of nonmetal?
ex. hydrosulfuric acid
what happens to acids name w/ polyatomic ions when its ending with "ate"?
what about "ites"?
: - ous
What happens to the ending if it the ion has one less oxygen? two less oxygen? one more oxygen?
one less oxygen
: ending with -ite
two less oxygens
: hypo - - ite
one more oxygen
: per- -ate
Explain Arrhenius acid and base?
: breaks apart, produces proton H
they are also always BL acids
: breaks apart, produces OH-
Distinguish between Bronstead Lowry acid and base?
: donates a p+
: accepts a p+
Explain what lewis acid and base are?
: accepts a pair of e- (has empty orbita)
: donates a pair of e- (extra e- pair)
What are amphotheric substances and how do you recognize them?
substance that can accept or donate protons
has both H+ and -ve charge
how do you recognize which is conjugate acid and conjugate base?
acids always donates
acids becomes conjugate base
H3O+ is always a conjugate acid
OH- is always a conjugate base
Define the terms storng and weak in terms of acids and bases.
strong acids and bases
: dissociate completly into ions in water, haigh affinity for water and have no reverse therefore no equilibrium
Weak acids and bases
: do not dissociate completely, low affinity fo water, reverse reaction an therefore equilibrium, dissociate less than 5%
How do you identify strong or weak acids and bases by thier formulas?
: H(halogen) except for HF, O-H = 2 or greater
: O-H =less than 2, all organic acid
: bases that include metals from group 1 or group 2 - except berylium
weak bases- alss organic bases, transition metals
Write balances acid and base dissociation equation.
: always add water
: if arrhenius, then no H20
if BL, then add water
weak acids and bases have an equilibrium arrow
