Group B – Prepare the diluted ferric nitrate solution:

1. On Datasheet 1, record the exact molarity of

the Fe(NO3)3 solution and the KSCN solution.

Be sure to include all significant digits.

2. Condition a 10 ml pipet with the stock solution.

3. Acquire ~15 ml of 0.0250 M Fe(NO3)3 solution

in a 50 ml beaker.

4. Pipet 10.00 ml of Fe(NO3)3 solution

into a 100 ml volumetric flask.

5. Acquire ~90 ml of 0.5 M HNO3 in a dispenser bottle.

6. Using a funnel, add ~15 ml portions of the HNO3

to the volumetric flask slowly. Stop and swirl.

Then continue with the next addition.

(Note: When you get close to the fill line,

add the HNO3 dropwise until the bottom

of the meniscus is on the line.)
