Protecting Marble from Acid Rain

Hard
Protecting Marble from Acid Rain | Science Fair Projects | STEM Projects
Acid rain is a serious problem that can cause damage to buildings and sculptures made from marble. But there's a way to protect marble from acid rain: calcium oxalate! This science project will show you how to apply calcium oxalate to marble and measure its effectiveness in protecting against acid rain.

Hypothesis

The hypothesis is that the marble surface coated with calcium oxalate will show the least amount of decay.

Method & Materials

You will clean three marble tiles, apply different coatings to each, and measure their weight in an acidic solution over time.
You will need three marble tiles, oxalic acid, a commercial marble sealant, beakers, vinegar, a measuring cylinder, a cloth, sandpaper, and a digital weighing scale.

Results

The results showed that the marble tile coated with calcium oxalate dissolved the least in the vinegar solution. This proves that calcium oxalate is an effective way to protect marble from acid rain.

Why do this project?

This science project is interesting because it shows how a simple solution can be used to protect a valuable material from a serious environmental problem.

Also Consider

Variations of this project could include testing different methods of applying the coating of oxalic acid (e.g. spraying, dipping and polishing) or repeating the experiment with limestone instead of marble.
