Inggi : Hello dhea, I'm fine. And you?
Dhea : I'm fine too. I have a question for you.
Inggi : What is
that?
Dhea : If the nail
is inserted into the water what effect will occur?
Inggi: Hmm, The nail inserted into the container containing the water are corroded due to the presence of O2 and H2O.
Inggi: Hmm, The nail inserted into the container containing the water are corroded due to the presence of O2 and H2O.
Dhea : okey inggi, thank you. Now I understand.
Inggi : you’re welcome de.
How the process of corrosion on the spikes?
BalasHapusIn corrosion events, the metal undergoes oxidation, while oxygen (air) is reduced. The metal rust is generally an oxide or carbonate. The chemical rust formula is Fe2O3.nH2O, a solid brown-red substance. Corrosion is an electrochemical process.
Hapushai inggii.. can you explain How to Iron corrosion prevention techniques well?
BalasHapusHere are the ways - how to prevent corrosion, namely:
Hapus1. Painting: Bridges, fences, and railings are usually painted. Paint avoids the contact of iron with air and water.
2. Oil or Grease: This method is applied to a variety of tools and machines. Oil and grease prevents iron contact with water.
3. Wrapped With Plastic: a variety of items, such as dish rack and basket basket wrapped with plastic. Plastic can prevent the contact of iron with air and water.
Would you please explain about corrosion and what causes corrosion?
BalasHapusCorrosion very often we encounter in everyday life. Another name of corrosion is also called rust. Corrosion itself generally occurs in metal objects such as iron. Corrosion is the reaction between the metal with the surrounding substances such as air and water causing new compounds. In the composition of the new compound is a solid color brown reddish fragile and porous.
HapusCorrosion occurs because of the reaction between the metal and the substances around it. In rust, rust can occur because moist air (oxygen and water) corrodes (reacts) to the iron so that a new substance appears, reddish brown solids.
Why some people soak the nails with salt water? What causes and consequences?
BalasHapusBecause a process of rusting is related to the level of basicity of an environment (in this case a brine solution). In a brine solution, the base concentration is much higher than ordinary water, therefore, the nails rust faster in salt water
