Ryan Agro Acid Rain Lab Purpose: I.V: Type of Stone D.V: Mass of rock after 5 days Control: Stone in Water Problem Statement: Acid rain causes some stones to loose mass. Which type of Stone is the best to prevent a loss in mass? Hypothesis: If the material used is affected by acid rain, then it will lose mass when exposed o vinegar, because of chemical changes. Procedure: 1. Gather Materials(container with lid, graduated cylinder, vinegar, balance, limestone, marble, red sandstone, granite) 2. Use the balance to get the mass of the limestone 3. Record the mass in grams 4. Measure 10mL of vinegar with the graduated cylinder 5. Put the limestone in the plastic container 6. Pour the vinegar on 7. Repeat steps 2-6 for each type of stone 8. Wait 5 days 9. Measure the mass of each stone and record your data Type of Stone | Starting Mass of Stone in Vinegar | Ending Mass of Stone in Vinegar | Starting Mass of Stone in Water | Ending Mass of Stone in Water | Change in mass of the Stone in Vinegar | Change in Mass of the Stone in Water | Marble | 6.5g | 5.5g | 6.5g | 6.5g | 1g | 0g | Granite | 6.5g | 6.5g | 6.5g…show more content…
The Marble lost one gram of mass because it was affected by the vinegar. The Granite and the Sandstone were not affected by the vinegar. The worst stone to make the statue out of is the Limestone because it lost one and a half grams of mass. The best for the statue would be the Granite or the Sandstone because they didn’t loose any mass. All stones exposed to water did not loose any mass. Since Vinegar is a simulator of acid rain we can predict that Granite and Sandstone should be used. I could have gotten better data if I used a more precise scale. My scale only measured to the half of a gram so it was hard to find a change in mass. Also I could have used the same shape of stone because surface area could have been a
