Title of your project
Abstract:
Part 1: Which of the two elements is the biggest pollution threat when dissolved in water?
Part 2: www.webelements.com/ www.wavecrestdiscoveries.com/water.htm/ Handbook of Chemistry and Elements 56th Edition.
Part 3: Zirconium is the worst in the toxicity, carcinogenic, and corrosive category. It is also tied for abundance.
Part 4: The worst one over all is Zirconium because it has three wins and 1 tie in the category.
Introduction:
Part 1: Solubility- The quality or condition of being soluble.
Melting Point- A temperature which a solid becomes a liquid.
Toxicity- Level of toxic.
Common Uses- The way something is mostly used.
Carcinogenic- Causes Cancer
Corrosive- Destructive or harmful
Abundant- Plentiful
Part 2: Iridium is most commonly used in cellular phones. It is used for making meter bars in France a lot. Zirconium is commonly used for many kinds of tubes. It is very spontaneous.
Part 3: This
is a major problem that needs to be fixed. Iridium and zirconium are getting
into out water supply. They get in off of land fills when people throw away
their cell phones and vacuums. We need water to live. We cannot go more than a
few days without water. The food we eat, such as fish, live in the water. We
would lose the ways to live.
Part 4: This project had much research from many different places. I used the internet a lot. A little was composed from books such as the encyclopedia.

Part
2: 
People throw away their vacuums and cell phones, and that gets into the water because of landfills.
Discussion/Conclusion:
Part 1: Iridium is insoluble and Iridium Sulfate is also. Iridium Nitrate is 0.000220. Zr(SO4)2 is soluble, but Zirconium and ZrN are insoluble. The for Iridium is 2466° IrS2 is 11.665°, IrS2 is 300°, Zirconium is 1830°, Zr(SO4)2 is 410°, and ZrN is 2980°. Iridium and all of it’s compounds have no toxicity and Zirconium and all of it’s compounds are low on solubility. Common uses for Iridium is cell phones and zirconium is tubes and tubing. Iridium and all of it’s compounds are not carcinogenic nor are the Zirconium compounds, but Zirconium itself is. All of Iridium and it’s compounds are very corrosive and Zirconium and it’s compounds are corrosive. Iridium and Zirconium and fairly abundant but their compounds are not.
Part 2: Zirconium is the biggest threat because it is Soluble, is toxic, may be carcinogenic, is corrosive, and is fairly abundant.
