WHAT CHEMICAL WILL DISSOLVE RUST THE BEST?
• Out of 6 chemicals which will dissolve rust the best
RESEARCH
• Research
– I researched how to get clean medal rusty in short times
–
–

–
I researched about different chemicals that are not deadly or poisonous
Researched how to handle chemicals that could be dangerous
Researched what makes rust dissolve or go away
Researched how to handle rusty metal not to get hurt or injured

HYPOTHESIS
• If I take 6 pieces of rusty metal and test which chemical removes the
rust best then the naval jelly will work best because it is often used to
get rid of rust.

Materials:
Procedures: 1st: use salt and water
Metal
to make the metal rusty 2nd: Put all
Salt
The chemicals in aluminum tins 3rd: put
Water
The metal into the chemicals and let them
Coca-cola
sit for 24 hours 4th: take out the metal and
Naval jelly Record data.
Lemon juice
Vinegar
Nail polish remover
Rubbing alcohol
Aluminum tins
Tongs
VARIABLES
• Constants: The amount of time the metal was in the chemicals.
• Controlled variables: The amount of rust on the metal at the end of the
24 hours.
• Independent (manipulated) variable: Which chemicals were used.
• Dependent (measured) variable: The amount of rust left on the metal,
depending on which chemical was used.
DATA/OBSERVATIONS
• Chemicals with acid worked best same with the naval jelly. After the
24 hours the rust on the lemon juice and naval jelly was almost all the
way gone.
CONCLUSION
• Chemicals with acid in them work very well along with naval jelly and
vinegar. Naval jelly works the best for removing rust, although lemon
juice also worked very well. Nail Polish remover worked the worst. My
hypothesis was supported.
