Expt: E Spectrophotometric Iron Determination

Question 1

Formula need to know

Answer 1

C1V1 = C2V2

C2 = C1V1/V2

Question 2

What is concentration of standard one solution?

Answer 2

8.00ml aliquot

Stock soln = Fe^2+ = 4.197x10^-4 mol/L

Question 3

Graph stuff

Answer 3

Absorbanc is Y axis

Concentration is X axis

y = mx + b

mx = m
c = x
b usually 1.00 cm

Beers law = A=ebc

Y-intercept is expected to me 0

More absorbent is how well your species absorbs light.
It is wave length of dependent. (relates molar absorptivity with concentration.)

Doesn’t absorb well at 600nm wave length
