Here are 20 examples of substances that dissolve in common acids (like hydrochloric acid, sulfuric acid, or nitric acid), with the understanding that some may dissolve slowly or under specific conditions:
Metals:
1. Iron (Fe): Reacts with acid to form iron salts and hydrogen gas.
2. Zinc (Zn): Reacts with acid to form zinc salts and hydrogen gas.
3. Magnesium (Mg): Reacts with acid to form magnesium salts and hydrogen gas.
4. Aluminum (Al): Reacts with acid to form aluminum salts and hydrogen gas.
5. Copper (Cu): Dissolves in nitric acid to form copper(II) nitrate.
6. Silver (Ag): Dissolves in nitric acid to form silver nitrate.
7. Gold (Au): Dissolves in aqua regia (a mixture of nitric and hydrochloric acids).
8. Calcium (Ca): Reacts with acid to form calcium salts and hydrogen gas.
Other substances:
9. Sodium bicarbonate (NaHCO3): Reacts with acid to form carbon dioxide gas, water, and a salt.
10. Calcium carbonate (CaCO3): Reacts with acid to form carbon dioxide gas, water, and a calcium salt.
11. Sodium hydroxide (NaOH): Reacts with acid to form water and a salt.
12. Potassium hydroxide (KOH): Reacts with acid to form water and a salt.
13. Ammonia (NH3): Reacts with acid to form ammonium salts.
14. Sodium chloride (NaCl): Dissolves in water, and the solution can then react with acid.
15. Sugar (C12H22O11): Dissolves in water, and the solution can then react with acid.
16. Ethanol (C2H5OH): Dissolves in water, and the solution can then react with acid.
17. Baking soda (NaHCO3): Reacts with acid to form carbon dioxide gas, water, and a salt.
18. Lime (CaO): Reacts with acid to form calcium salts and water.
19. Marble (CaCO3): Reacts with acid to form carbon dioxide gas, water, and a calcium salt.
20. Chalk (CaCO3): Reacts with acid to form carbon dioxide gas, water, and a calcium salt.
Remember:
* This is not an exhaustive list, and there are many other substances that can dissolve in acids.
* The rate of dissolution varies greatly depending on the acid, the concentration of the acid, and the temperature.
* Many reactions between acids and substances are exothermic, meaning they release heat.
* Always handle acids with caution and wear appropriate safety gear.
