Chemically clean an iron nail from rust, assuming that the composition of the rust includes iron oxide (3) and iron hydroxide (3)
To remove rust from a nail, you need to find a substance that will react with iron oxide and iron (III) hydroxide to form new substances.
Sulfuric acid can be such a substance.
The equations of chemical reactions are as follows:
2Fe (OH) 3 + 3H2SO4 = Fe2 (SO4) 3 + 6H2O.
Fe2O3 + 3H2SO4 = Fe2 (SO4) 3 + 3H2O.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
