1: Measure Absorbance versus Concentration for
Record your data in Table 44.1
1. Take five clean 50 mL volumetric flasks from the Containers
shelf and place them on the workbench.
1. Fill the flasks with the following amounts of 0.060 M
copper(II) sulfate and 1 M nitric acid found in Table 44.1.
2. Obtain 5 cuvettes from the Containers shelf. Transfer 3 mL
from the first flask into the first cuvette, from the second flask
into the second cuvette, and so on until all five cuvettes are
filled.
3. Use the dilution formula, M₁ V₁ = M₂V/₂, to calculate the
concentration of Cu²+ ions in all 5 cuvettes. Record these
concentrations. Note: there is 1 mole of Cu²+ in 1 mole of
CuSO4 so [Cu²+] =[CuSO4].
4. Obtain another cuvette from the Containers shelf and place it
on the workbench. Add 3 mL water. This is the blank cuvette.
5. Take a Spectrophotometer and place it on the workbench.
Place the blank cuvette into the spectrophotometer. Check to
make sure the spectrophotometer output is still absorbance
(A). Set the wavelength to 700 nm. This is the Amax for copper
ions. Press the Zero button.

Expert Solution

Step 1

Note the following in the given dilution formula and solve for M₂.

$M_{1} V_{1} = M_{2} V_{2} M_{1} = C o n c e n t r a t i o n o f C u^{2 +} = [C u^{2 +}] = [C u S O_{4}] V_{1} = V o l u m e o f C u S O_{4} M_{2} = F i n a l c o n c e n t r a t i o n o f C u^{2 +} = ? V_{2} = F i n a l v o l u m e$
