Transcript of CHEM 151 Final Project Presentation

• Questions
o Which paint bind
er
will help to create the best color durable qualities?
o Can a mixture of
pain
t binders work efficiently?
Water was the bes
t

pr
ussian blue paint binder due to its polarity.
The mixture of binder
s

wo
rked efficiently in the forest green due to the nume
rous
properties granted by the mixture.
• Reasons for Accuracy: Perc
ent
Yield
For every .3 grams of
prussian
blue made, only .241 grams was produced.
For every .3 grams of forest
blue
that was made, only 0.153 grams was produced.
o Products were formed
 Less products were created
than expec
ted
• Certain conditions weren’t met
• Dynamic equilibrium vs. comple
tion
• Improvements for the future
o Create extra paints just in case of l
os
s of substances or in case reactions does not proceed as ex
pe
cted
o Also create more so all paint pigments have one control and at least one other variable to compare pigments

It's time to analyze
Experimental Design
Prussian Blue
.287 grams
.408 grams
mixed
15mL
mixed
50 mL beaker
Centrifugation!!!!
Extract onto weighing paper and leave to dry
Separate, add paint binders, and mix!
Paint Binder 1 (Water/control)
0.5 mL
Paint Binder 2 (Cooking Oil/hydrophobic)
0.5 mL
Prepare Paint Binders!!!!
Paint Binder 3 (Honey/high viscosity)
0.5 mL
Get to paintin'!!!
Now to

Forest Green
Forest Green
Evidence/Data
Before
After
The Mascot (say whaaaa!!!!!)
Claims
For prussian blue, water was the best paint binder
Overall, the forest green was the best paint mixture.
WHY????
.540 g Cu(NO3)2*2.5H2O (Copper (II) Nitrate Hydrate)
.24487g Na2S or 31.3775 mL (Sodium Sulfide)

Introduction!!!
Extract onto weighing paper
• Inorganic pigments are synthesized through chemical reactions that are based on transition metal oxides.
• Transition metals are typically used in the synthesis of inorganic pigments because of the bright and vivid colors they produce.
• Inorganic pigments are used because they do not bleed, are heat and light stable and are much cheaper than organic pigments.
• To determine a set of procedures to create inorganic paint pigments and find a great paint binder
• Questions
o Which paint binder will help to create the best color endurant qualities?
o Can a mixture of paint binders work efficiently?
• Prussian Blue
o The best paint should be made with water
• Forest Green
o The mixture of different paint binders will produce the best paint.

Linseed (0.7 mL)
Honey (0.1 mL)
Ethanol (3 drops from pipette)
Paint on shirt!!!
Iron (III) Chloride Hexahydrate
Potassium Ferrocyanide Trihydrate
Chemistry Lab Fun!!!!
Thank you for EVERYTHING you've done for us, Sam Solano!!!
Put painted shirt with all the paints on it in the washer (no detergent) and air dry.
Chemical Thinking is cool.
We love you!!!!!
