What to do if the iron rusts, how to remove the rusty iron

Purpose: Conditions for the formation of rust.

Experimental materials: prepare a number of iron nails of the same material and equal quality.

Experimental Procedure:1The 20 iron nails were placed in 4 beakers on average, and the beakers were marked with four groups: A, B, C, and D.

�2.Place tap water in a group A beaker.

�3.Seal the Group B beaker with fuse film and put nothing in.

�4.Use a pencil to apply a layer to the nails in group C to isolate the nails from the air. (The reason is that the pencil is composed of carbon and clay, and the carbon element is chemically stable at room temperature and does not react chemically with air).

�5.Place the four sets of beakers A, B, C, and D in the same place and wait long enough.

Results: Rust was found on the nails of group A, and the rust was obvious.

Group B nails have almost no rust.

Group C nails are completely free of rust.

The D group nails also have only some rust and almost no rust.

Experimental conclusion: humidity and the amount of air are the main conditions for ironclad rusting. The higher the humidity and the more air, the more likely it is to rust.

After the experiment, it occurred to me that if the iron railing was isolated from air and water, then the railing might not be as rusty as it was. Therefore, in order to avoid rusting nails, people need a lot of substances to isolate iron from air.

For example, people will spray plastic on some things made of iron, and the plastic is chemically stable at room temperature, effectively isolating iron and air, making iron almost rusty, and also has a beautifying effect.

How to remove the rusty iron.

Soak it in vinegar first, wipe it dry after the rust is gone, and paint it with paint to prevent rust from recurring next time. However, do not directly use paint to remove the rust of the iron, otherwise the rust will be even more amazing.

Iron rust can be removed with the help of lemon, potato peels, vinegar, and cola.

1. Lemon: Lemon contains citric acid.

Acids can neutralize chemical reactions when they encounter basic elements.

After various reactions have taken place, the properties of the stain have been destroyed, and the rust can be removed very quickly.

2. Potato skin: Spread the rust with a small amount of salt dipped in the potato skin and spread it to the rusty place of the iron pot. Potato peels not only relieve pain and reduce swelling, but also remove tea stains from teacups.

3. Vinegar: edible vinegar also contains acid, which can decompose and react with rust.

However, after the vinegar undergoes a chemical reaction, it will continue to corrode the iron, so that the surface of the iron will no longer be smooth and more prone to rust. Therefore, when choosing to use edible vinegar, you should use hot vinegar, and the cleaning time should not be too long to prevent the iron from being corroded.

4. Coke: The reason why cola can remove rust is because cola contains carbonic acid and can undergo ionic reactions.

Oxidizes rust, but drinks leftover cola prevents carbon dioxide long after.

The function of draining to remove rust is relatively small, so use a freshly opened Coke.

The reason why iron rusts easily

Iron is prone to rust, mainly due to its nature. Iron is a relatively reactive metal, which means that it can easily react chemically with other substances. There is oxygen in the air, and iron will undergo a chemical reaction when it encounters oxygen, and the main component of rust is iron oxide formed after the reaction of iron and oxygen.

In addition, carbon dioxide in the air, salty water, impurities contained in the iron itself, and rough and unclean surfaces can cause iron to slowly rust. In a humid environment, iron rusts easily; Conversely, iron is less susceptible to rust in dry conditions.

What to do if the iron is rusty 1, put the iron into the fire to heat, then turn off the fire, take out the iron, dip some vinegar with a rag, and directly wipe the rusty parts of the iron, you can remove the general rusty iron, soak it in thicker rice water for about 2-3 hours, and then prepare to boil rice water. 2. After the rice water is boiled, pour it out after the rice water is cooled, rinse the iron with clean water, you can remove the rusty iron, use sandpaper or whetstone to grind the rust off, and rinse the iron with clean water to remove the rusty iron.

The iron is rusty and can be pickled.

Iron oxidizes in a humid environment to form ferric tetroxide, or rust, which reacts with acid to replace iron. But vinegar does not work, and the acid that displaces iron must be a strong acid, such as hydrochloric acid or dilute sulfuric acid.

Rusting iron products can be put into hydrochloric acid to achieve the effect of rust removal and wash away the rust on the surface of the iron. After the iron rust removal is completed, it is best to carry out another step of rust prevention treatment, that is, put the iron parts into the anti-rust protective agent and soak them for a minute or two, so that there is no need to worry about the iron parts rusting here.

1. Remove with white vinegar and baking soda.

Vinegar and baking soda are commonly used cleaning artifacts in kitchens, and they can also be used to remove rust. Prepare half a bowl of white vinegar, add baking soda to it, stir well, pour the stirred white vinegar baking soda into the rusty iron pot, after a while you will find that the white vinegar baking soda has become cloudy, this time it indicates that the rust has been dissolved, then wipe the rust with a steel wool ball, you will find that the rust is easily erased.

If you don't have baking soda at home, just white vinegar is also used to remove rust. After heating the iron pot, turn off the heat, then dip a little white vinegar on the rag and wipe the rusty parts with a rag, which can also remove the rust.

3. Add salt to remove the potatoes.

Potatoes contain an amylase, which can decompose rust, and salt, which is coarse, can act as a friction agent, and the combination of these two ingredients can remove rust well. The method is also very simple, pour some salt into the iron pot, then take a potato, cut the potato and dip it in some salt, and use it to rub the rust.

Fourth, use the peel to remove rust.

The flesh of pears is sweet, juicy, cool and delicious, many people love to eat them, after eating pears, don't throw away the peel in a hurry, use it to remove rust from the pot. The reason why the skin of pears can remove rust is because of the adsorption properties of the peel oil. Put the collected pear skin into the pot, add some water ** and boil, you can see that while the water is boiling, the rust in the iron pot is gradually removed.

1. Put the iron into the fire to heat it, then turn off the fire, take out the iron, dip some vinegar with a rag, and directly wipe the rusty parts of the iron, you can remove the general rusty iron, soak the traces with thicker rice water for about 2-3 hours, and then prepare to boil the rice water.

2. After boiling the rice water, pour it out after cooling, rinse the iron with clean water to remove the rusty iron, use sandpaper or whetstone to grind the rust off, and rinse the iron with clean water to remove the rusty iron.
