What are some liquids that remove rust?

Answer 1

when liquids such as water etc are spilled or applied to metals or even rain this causes the metals to wear out and start rusting that is why we have to protect gardening tools and other metal ojects from rusting. this can be prevnted by lubricating or oiling the tools

Answer 2

== == First off, understand that rust is Iron Oxide -- iron atoms that have combined with oxygen atoms.

Because iron can occur in two ionized forms (Fe2+, where two electrons are missing, and Fe3+, where three electrons are missing), iron oxide can occur in three forms. These forms are called Ferrous Oxide (FeO), Ferric Oxide Fe2O3, and Ferrous Ferric Oxide (Fe3O4).

This little digression was to show that rust is made by combining iron and oxygen. [Most of the iron available for mining in the earth's crust is in oxide form.]

Liquids that cause rust must have a supply of oxygen ions in the liquid. A common one is water (H2O). If you add salt to it (for example, sea water), the dissolved salt accelerates the rate at which the Iron + Oxygen reaction occurs.

Another common liquid is Hydrogen Peroxide (H2O2). This has more free oxygen ions than pure water does. What you can buy in the drug store is usually diluted to about 3% H2O2 , with the rest being normal water.

Many acids will also enhance the corrosion of iron (and other metals).

One aspect of rust is that it is permeable to oxygen. This means that once a surface layer of iron-oxide has formed on the metal, more oxygen can continue to invade the interior and form rust.

By contrast, there are some metals, notably aluminum, whose oxide surface layer is impermeable to oxygen. So, Aluminum forms a self-protecting skin layer of aluminum oxide (Al2O3), which protects the interior from oxygen and from oxidation.

Answer 3

Rust is combining iron with oxygen. Water (with dissolved oxygen or salt) can cause rust, as will exposure to acids, such as vinegar, and things containing acids (soft drinks, fruit juices) Other liquids, such as oils, prevent rust by shielding the iron from contact with oxygen,

Answer 5

Metals rust, and more than likely there is a liquid metal in whatever substance is rusting.

Answer 6

well i was doing a project on which liquid will cause rust and coke made the nail even shiner than usual... try it it might work but don't use vinegar water

Answer 7

Oil I know for sure!!
