Classify each substance as a strong acid, strong base, weak acid, or weak base.
NaOH, H2SO4, HF, HCl, HClO3, HBr, HNO3, HI, HNO2, HCN, LiOH, Ca(OH)2, CsOH, KOH, Ba(OH)2, CH3COOH, HCOOH, NH3, (CH3)2NH, CH3NH2
NaOH – strong (Li, Na, K, Rb, Cs, Ba, Sr, Ca hydroxides are all strong bases)
H2SO4 – strong acid
HF – weak acid
HCl – strong acid
HClO3 – weak acid
HBr – strong acid
HNO3 – strong acid
HI – strong acid
HNO2 – weak acid
CH3COOH – weak acid
HCOOH – weak acid
NH3 – weak
[CH3]2NH – weak acid
CH3NH2 – weak acid
all right but NH3 is a weak base
STRONG ACIDS
HCl
H2SO4
HNO3
HI
HBr
HClO4
____________
WEAK ACIDS:
CH3COOH
HF
HCN
HNO2
HCOOH

WEAK ACIDS:

CH3NH2
NaOH – strong base (Grp 1 hydroxides are strong)
H2SO4 – strong acid (diprotic)
HF – weak acid (exception to usually strong halide hydrogen acids)
HCl – strong acid
HClO3 – strong acid (chlorate, chlorite, perchlorate, hypochlorite pretty strong acids)
HBr – strong acid
HNO3 – strong acid (very strong, stronger than HCl)
HNO2 – weak acid (monobasic)
HCN – weak acid
LiOH – strong base (Grp 1 hydroxide)
Ca(OH)2 – strong base (kind of heavy Grp 2 hydroxide)
CsOH – strong base (Grp 1 hydroxide)
KOH – strong base (Grp 1 hydroxide)
Ba(OH)2 – strong base (kind of heavy Grp 2 hydroxide)
CH3COOH – weak acid (monoprotic, acetic acid, not much dissociation)
HCOOH – weak acid (carboxylic acids generally weak)
NH3 – strong base
(CH3)2NH – weak base
CH3NH2 – strong base
^^^ CH3NH2 is also a weak base
Classify each substance as a strong acid, strong base, weak acid, or weak base.
