Does a rusted nail weigh more?
Since iron gains oxygen when it rusts, and the iron from the nail won’t have gone anywhere, it will weigh more than it did before.
Does corrosion increase mass?
reignbough – In corrosion or oxidation, mass can increase or decrease depending on what happened to the product of the chemical reaction. For example, suppose you took an iron spike weighing 1 ounce, and subjected it to an environment that caused heavy oxidation (or rust) to form.
Do rusted weights weigh more?
Some of the iron is converted into iron oxide-rust. The oxide will weigh more than the iron did. Some of the iron will become ferric or ferrous ions in the water giving you a slight loss.
Does rusted metal weigh more?
When iron or any other metal oxidizes, oxygen from the air combines with the iron to make iron oxide or rust. So the weight increases, due to the increased weight of oxygen which has combined with the iron.
Do rusted weights weigh less?
Some of the iron is converted into iron oxide-rust. The oxide will weigh more than the iron did. The biggest problem will be the amount of water that the rust hydrates or mechanically retains.
Is rusted metal heavier?
When rust forms, the mass of the iron object is increased by the mass of oxygen that has combined with some of the iron.
Does rust change the mass of an object?
Both iron and oxygen atoms have a finite mass, so rusting leads to a general increase in mass.
Does rust affect weight?
Notes: When iron or any other metal oxidizes, oxygen from the air combines with the iron to make iron oxide or rust. So, weight of the bar increases, due to the increased weight of oxygen which has combined with the iron.
Do rusty weights weigh more?
A. Some of the iron is converted into iron oxide-rust. The oxide will weigh more than the iron did. Some of the iron will become ferric or ferrous ions in the water giving you a slight loss.
Does rust make metal weaker?
Rust can affect iron and its alloys, including steel. Rust causes the metal to expand, which can place great stress on the structure as a whole. At the same time, the metal will be weakened and become brittle and flaky. Rust is permeable to air and water, so the metal beneath the rust layer will continue to corrode.
Does rust make things weaker?
Rusting has a number of effects on metal objects. It makes them look orange and rough. It makes them weaker, by replacing the strong iron or steel with flaky powder.
Does rust make metal heavier?
So any iron that has turned to rust will weigh the original weight of the iron that has rusted away, plus the weight of the oxygen that has combined with it to form the rust. If you could successfully collect all the rust, the rusty nail plus its rust would always weigh more than the non-rusted one, every time.
Which is the best way to measure rust?
So the real way to measure corrosion is is to weigh the nail before you start; then after the rusting period you rub off all of the rust, let it dry, and weigh how much raw metal is left. It will always be less that you started with because some of the iron was consumed as rust and you are not including that in the weigh-off.
Can a rusty nail weigh more than a non rusted nail?
But you usually can’t. The rust goes into solution and makes the water rusty, it washes away, it rubs off, etc. So depending on how much rust has rubbed off or floated off into the water, a rusty nail may weigh more or less than the original non-rusted nail.
What does rust look like in a dish?
Both dishes had significant rust, the general look of it being like a non-coagulated waste water treatment precipitate, extremely light and fluffy, like a brown cloud in the sky, lying on/near the bottom. The dish with the saltwater had a white precipitation ring above the solution level, apparently at about the original solution level.
