__Problem Statement__
What type of acid will corrode copper the most?

__Research__
Corrosion is the weathering away of metals concluding in rust or there being missing parts in the metal. There are different types of corrosion Galvanic and Crevice Corrosion. Galvanic Corrosion is when two different metals have electrical or physical contact with each other and are in a common electrolyte (which is any substance containing any free ions). Crevice Corrosion is when the metal is getting corroded thorough small crevices in the metal.
 * Corrosion

=**__ Hypothesis __**= If I use Aluminum Brightener then it will corrode the copper the most.

__Independent__
Type of acid

__Dependent__
How much is corroded

__**Controlled**__

 * Type of material
 * Amount of acid
 * Acid Concentration
 * Time
 * State of material

__**Materials**__

 * Aluminum Brightener
 * Bleach
 * Vinegar
 * 3 pennies
 * 3 Measuring cups
 * Timer

**__Procedure__**

 * 1) Set up the cups
 * 2) Fill up the cups with one acid up to 30 mL
 * 3) Start the timer simultaneously as you drop in the penny
 * 4) Wait until 25 min. to take out the metal
 * 5) Repeat all steps 3 times the same and 3 times using 2 different acids.

__**Data**__
Aluminum Brightener = 70% Bleach = 10% Vinegar = 30%

__**Conclusion**__
I conclude that my hypothesis was correct and that Aluminum Brightener corroded the most = = = =

__**Data**__
Penny = 30 % Nickel = 40% Aluminum = 60%

__**Conclusion**__
I conclude that my hypothesis was correct and that Aluminum corroded the most

__**Data**__
10 mL = 30 % 20 mL = 50 % 30 mL = 75 %

__**Conclusion**__
I conclude that my hypothesis was incorrect and that 30 mL corroded the most
