How does the presence of salt accelerate the rusting process?

Salt speeds up the rusting process because salt water acts as an electrolyte, meaning that it contains ions that allow it to conduct electricity better. By adding more ions to the water, iron is prone to losing electrons more easily, which speeds up the rusting process

salt increases water's ability to carry a current at the surface of a metal which enhances the rate of electrochemical corrosion and rusting.

Saltwater speeds up rusting because it allows better electricity conduction, so iron can lose protons much faster.

So, how does iron loosing electrons cause it to form rust? What does it mean it gets deposited as rust?

Also, why does iron react with o2 and H2o as apposed to other metals?

salt increases water's ability to carry a current at the surface of a metal hence increase rusting

To further expand on rust, when Iron reacts with H2O (water) and O2 (oxygen), the product is iron oxide with the formula Fe2O2. When you search up iron oxide, you will see a reddish/brownish substance that is common to see when iron is oxidized.

The salt acts as an electrolyte that allows a current to flow, better conduction makes iron lose electrons more readily and faster
