IMPORTANT Flashcards
zero order reaction equation
at - a0 = -kt
zero order reaction graph
decreasing linear(concentration only)
first order reaction(equation)
lnat - lna0 = -kt
first order reaction(graph)
decreasing linear
second order reaction(equation)
1/at - 1/a0 = kt
second order reaction graph
if concentration: increasing exponential
if 1/concentration: positive linear
half life order equation
t 1/2 = 0.693/k
MUST KNOW STRON ACIDS
HCLO4(perchloric acid)
HCL03(choric acid)
HCL(hydrochloric acid)
HBr(hydrobromic acid)
HI(hydroiodic acid)
HNO3(nitric acid)
H2SO4(sulfuric acid)`
COMMON WEAK ACIDS
HSO4- (HYDROGEN SULFATE ION)
H3PO4(phosphoric acid)
HF(hydrogen fluoride)
HNO2(nitrous acid)
CH3CO2H(acetic acid)
for acid base reactions, if ka is less than 1.0*10^-3
you can ignore the x in [ha]0 - x
a strong acid DOES NOT
make a buffer
optimal buffering occurs when
[ha] = [a-]
[ha] = [a-]
ph=pka
[ha] > [h]
ph < pka
the solubility is affected by common ion effects
