What will happen if you put the rusting metals in the vinegar and alcohol?
Vinegar can corrode iron, alcohol not.
A mixture of water, vinegar, and bleach is corrosive to most metals. If pennies are placed in it, the copper will oxidize. Rusting is a term only applying to the oxidization of iron, not other metals. The pennies will look a lot cleaner and the liquid will turn blue. If you leave the pennies in the mixture too long, holes may start to form in them.
Acids (including dilute acids such as vinegar) are reducers- they will corrode metals. Vinegar may cause accelerated corrosion while (due to high water content) also oxidising (rusting) metals which are prone to oxidation. To accelerate the oxidation of metals, you require a stronger oxidising agent. However, using a dilute acid may enhance the oxidation process in metals which galvanise. Some metals do not 'rust' as they develop a protective oxide layer when exposed to oxidising…
Rusting is also called as the process of slow eating of metals. It takes place in various metals and has no fixed composition. Basically, it is the reaction of some gas and the moisture in the atmosphere with the metal which leads to rusting. Commonly we relate rusting with iron which reacts with oxygen in the atmosphere and forms iron oxide. Also, silver rusts too leading to its black colour.
Eating away and eventual destruction of metals and alloys by chemical attack. The rusting of ordinary iron and steel is the most common form of corrosion. Rusting takes place in moist air, when the iron combines with oxygen and water to form a brown-orange deposit of rust (hydrated iron oxide). The rate of corrosion is increased where the atmosphere is polluted with sulphur dioxide. Salty road and air conditions accelerate the rusting of car bodies.
Corrosion, or rusting, is the oxidation of a substance, and therefore a chemical reaction. The most well known corrosion is the rusting of iron, in which the iron is oxidised by oxygen. Both metals and non-metals can therefore undergo corrosion, and it can be by any oxidising agent, and therefore not need be oxygen.
