#4 menSafety Information:5. Excess hydrochloric acid may be present at the conclusion of the reaction. Take appropriateprecautions.6. Hydrochloric acid is corrosive. External contact can cause severe burns. If contact does occur, washthe area immediately with water for 15 minutes and notify your teacher. Contact with the eyes cancause permanent damage. If contact with the eyes occurs, use the eyewash station for 15 minutesand call an ambulance.7. Always wear appropriate goggles and aprons when handling this acid.8. After reviewing your procedure, the instructor will discuss any safety precautions that are specificto your experiment.Questions:4. What volume of 3.00M hydrochloric acid would you need to react entirely with a 4.25g piece ofseashell that contained 87.0% calcium carbonate by mass?5. Calcium carbonate decomposes upon heating. What are the products of the decomposition reaction?6. Limestone is used in the construction of many buildings. Explain how acid rain affects limestone.Report: Please submit your lab online in PDF format. Ensure your lab report contains the followinginformation: Title, Procedure, Data, Calculations, Conclusion, and answers to Questions. In theconclusion, be sure to include which eggshell colour had more calcium carbonate, and indicate anypossible sources of error.
