After letting it sit for a whole day all the lemon juices looked cloudy. The metals in the vinegar had bubbles form around them. The metals in water were unchanged.
We believe that out of the lemon juice, vinegar, and water the most acidic one will corrode the steel wool the most.

The lemon juice continued to get cloudier and the vinegar had a little rusting began in the steel wool jar, and water appeared unchanged from the day before when observed.
Lemon Juice
In this experiment lemon juice, and vinegar were used as the acids to corrode three metals; copper, aluminum, and steel wool. Water was the control liquid and all the metals were submerged in the liquids and concealed in jars.

The more acidic an acid is, the more it will rust an object.
All the lemon juice continued to get cloudier, and only the steel wool began to rust in the vinegar and water, the copper and aluminum remained the same.

Vinegar
On the final day of observations it was concluded that the aluminum only rusted a little in the water, and copper did not rust in any of the liquids, but the steel wool did rust in the vinegar and water, and the lemon juice remained cloudy for all of the metals.
In our hypothesis we thought that the most acidic one would rust the metals the most, however it turned out that the lemon juice had no effect on metals, whereas the vinegar had the greatest effect, and then the water.

In chemistry this experiment relates to acids and bases, and pH levels, and how they affect different objects. It is also decomposition of metals.
