How does tap water rust iron nails?

after 3 days of nails in tap water, it will begin the rusting process. If you put salt in the water, it will not rust.

It will rust faster in a salt water base and it will also rust faster in a tap water base not a sugary or a pop type, they have a slower fashion of rusting.

The oxygen in the water reacts chemically with the iron, to create iron-oxide and hydrogen. H2O + Fe = FeO + H2 which is wrong

no i think it would rust fastet in tap water

First of all Nails in salt water rust quicker. That's because salt is sodium chloride and that affects a nail by rusting it. No i did a experiment on which one rust faster. After 5 days the nail in the tap water rusted way faster than the nail in the salt water. With DISTILLED water, the nail will not rust as fast as the salt. TAP water will rust faster then salt.

you really should pay attention in class

Salt water contains Na+ & Cl- ions which are highly reactive with iron to form FeCl2 .So iron rust faster in salt water.

It rusts faster in salt water.

coke, vinegar, tap water, any other adequate acids

If both t etap water and the distilled water are open to the air and both have dissolved oxygen then the iron nail will rust faster in tap water. Rusting requires dissolved oxygen and goes faster if there are dissolved salts.

I put an iron nail in tap water and salt water and then purified water and salt water and both times the iron nail rusted faster in the tap and purified water versus the salt water.

tap water does have iron in it

Usually iron covered in enamel or chrome to rust-proof it.

because the salt removes the rust that is forming from the tap water

tap water will rust it faster. tap water lets more oxygen get to the nail and should cause it to rust in a few hours after being put in the water

I believe tap runs faster

yes any liquid can rust a nail

The nail will rust faster in salt water.

Water will cause iron and steel to rust ( Oxidise into FeO2 ). Dissimilar metals rust more quickly than pure metals as a result of electrochemical reactions, this is why steel rusts quicker than iron, also joints between dissimilar metals rust very quickly. Salt water will accelerate rusting because salt water is a better electrical conductor. rust is an endothermic reaction, so heat also speeds it.

Depends what nail you're using. For me, when I used an iron nail, it alternated the nails color. And for brass it also changed color, more lighter color of yellow. But I prefer you do the experiment for this to be successful for you and also see it with your own eyes.

Most likely salt water. Depending on the chlorine levels in the tap.

iron and calcium iron and calcium

Most likely salt water. The salt accelerates the rate of corrosion, plus it has the oxygen needed for the metal to rust. Tap water has the oxygen too but with the salt also, it would cause the metal to rust more rapidly.

It will eventually corrode (rust).

Distilled water will rust a nail faster as distilled water contains higher levels of OXYGEN which is what causes OXIDATION or commonly referred to as rust...
