Beer’s Equation

20
Q

What is the formula for Beer’s Equation

A

A = a b C
where,
o A = absorbance
o a = absorptivity coefficient (constant)
o b = length of light path (constant)
o C = concentration

21
Q

the absorbance of an
unknown concentration (u) of a particular constituent is
compared with the absorbance of a known concentration (s)

A

spectrophotometric analysis

22
Q

states that the power of a transmitted radiant beam decreases exponentially as the thickness of the solution containing the absorbing chemical species increases
arithmetically

A

LAMBERT’S OR BOUGUER’S LAW

23
Q

combination of the above laws and relates the power of the
incident beam and transmitted beam to the thickness and
concentration of the solution containing the absorbing
chemical species

A

BEER-LAMBERT’S / BEER-BOUGUER’S LAW

24
Q

True or false
↓ conc. solute = ↓ light abs = ↓ transmitted light

A

False
↓ conc. solute = ↓ light abs = ↑ transmitted light

25
Q

True or false
↑ conc. solute = ↑ light abs = ↓ transmitted light

A

True

26
Q
