Beer's Law- midterm Flashcards
1
Q
beers law allows us to
A
quantify the amount of drug in products and eventually concentration
2
Q
what is beers law equation and what each term represents
A
Abs=As l C abs= absorbance as= absorptivity c= concentration l= path length
3
Q
5 things that affect absorbance
A
- temp= affects path length and concentration
- wavelength= affects absorbance and abs
- path length
- concentration
- solvent system
4
Q
max absorbance is
A
peak corresponding lambda is lambda max
5
Q
max absorbance corresponds to
A
lambda max
6
Q
describe beers law curve
A
forms a straight line and relationship between absorbance and concentration is linear
7
Q
relate beers law equation to y=mx+b
A
y–> Abs
m–> As *l
x–> C
B +0
8
Q
for beers law equation slope must be
A
positive
9
Q
absorbance is not the inverse
A
of transmittance
10
Q
absorbance values are affected by
A
temperature
11
Q
changing the solvent system should
A
affect the absorbance reading
