Corrosion is really a redox reaction - involving the transfer of electrons.
Salt water is better at carrying charge than fresh water, so it 'helps' to speed up the reaction, as the charge can be transferred by the mobile (sodium and chloride) ions more readily.
Yes, salt does affect rust. In fact, applying saltwater on top of a metal will help to speed up the actual scientific process of rusting.
Any type of water will rust metal but salt water is worse because depending on the properties of your metal it might also corrode.
It is not mandatory but halogens ions amplify the corrosion.
Corrosion is accelerated in salt water; culpable is the ion chloride.
I affect the speed of rust.
blocks
yes.
Water. Water combined with sea salt will increase the speed of the nail rusting.
If by non rusting you mean it is in the same state it was made in then it wouldn't be part of any change. But if something is rusting it would be a chemical change because the metal is changing composition and it is not the same metal it was in the first place.
Rain water is fresh water and does not have salt. Saltwater is not fresh and does have salt.
no rusting iron is not a physical change it is a chemical change
yes
Saltwater is a very powerful catalyst for the process of rusting.
Rusting is an irreversible process.
Yes salt water speeds up the rusting process.
saltwater, regular water, and vinegar can all speedup the rusting of a penny
Water. Water combined with sea salt will increase the speed of the nail rusting.
be cause
Yes, rusting is a very important problem for all iron structures.
Iron rusts better in salt water. The salt helps speed up the process of rusting.
Yes, saltwater is corrosive for Iron and will cause Iron to rust.
Steel castings can prevent rusting depending on what the kind of steel. Carbon steel may cause rusting at a higher rate than stainless steel.
When rust forms on a nail the dark brown colour is the characteristics of rusting.
