What happen when nitric acid is added to egg shell |
| Answer» Egg shell\xa0is made of calcium carbonate. We know that when calcium carbonate reacts with\xa0nitric acid, it gives carbon dioxide, calcium nitrate and water. Same reaction\xa0happens\xa0when\xa0nitric acid\xa0is poured over\xa0egg shell.\xa0Upon mixing of concentrated\xa0hydrochloric acid\xa0and concentrated\xa0nitric acid, chemical reactions occur. These reactions result in the volatile products nitrosyl chloride and chlorine gas:HNO3\xa0(aq)\xa0+ 3\xa0HCl\xa0(aq)\xa0→ NOCl\xa0(g)\xa0+ Cl2\xa0(g)\xa0+ 2 H2O. as evidenced by the fuming nature and characteristic yellow color of aqua regia. | |
