Rusting is accelerated in the presence of the ion chloride.
Yes, rust happens to iron nail though it is kept in distilled water.
When an iron nail comes in contact with a chemical that absorbs water vapor, such as silica gel or calcium chloride, the chemical will absorb the moisture from the air around the nail. This helps prevent the nail from rusting, as rusting is a chemical reaction that occurs when iron comes in contact with water and oxygen. The chemical desiccant helps keep the nail dry and prevents the conditions necessary for rusting to occur.
The nail will start to rust due to exposure to water and oxygen. Rust is a chemical reaction called oxidation, where the iron in the nail combines with oxygen in the presence of water to form a new compound. This process can cause the nail to weaken and eventually corrode over time.
Because of chemical reaction
What happens is that you can see that the density of a nail is more than the density of water and that the density of a cork is less than that of water.
it would rust
The water and the air makes a chemical change to the nail to make it rust
To an extent, some of the iron from the nail will combine with dissolved oxygen in the water to form Iron Oxide. That material was not present when you introduced the steel nail and the water, so it is new to the system. No additional matter was created, of course.
It's not just saltwater that makes a nail rust, even water makes a nail rust. Rust is simply oxidation, it happens when oxygen comes into contact with something and creates a chemical reaction and creates "oxides". Iron + oxygen = Iron oxide (red rust on steel)
When a copper nail is dropped in a copper sulfate solution, a redox reaction occurs. The copper nail will act as a reducing agent, transferring electrons to the copper ions in the solution. This reaction will cause the copper ions in the solution to plate onto the surface of the copper nail, forming a layer of solid copper.
The water becomes murky and the salt rises to the top
The hammer exerts a force on the nail; the nail exerts a force on the hammer.
