How to prevent corrosion of aluminum sheet surface?
- Directly on the surface coating H2SO4Because the AL and H2SO4 react to produce a dense oxide film that prevents corrosion again, the barrel containing sulfuric acid can be made from ALs
is copper wire really better than aluminum?
- yes copper wire is better than almunium since coppe is very best conductor that that of almuniums
why lye and aluminum shouldn't be mixed?
- Under normal circumstances, aluminum does not react with water, as an impermeable protective layer composed of aluminum hydroxide either forms within seconds or is already in place. With the addition of sodium hydroxide, the formation of a protective layer is prevented. With the production of aluminates [ Al(OH)4 ]-, the amphoteric (capable of acting as either an acid or a base) aluminum hydroxide Al(OH)3 goes in solution: 2 Al + 6 H2O -- 2 Al(OH)3 + 3 H2 Al(OH)3 + NaOH -- Na+ + [ Al(OH)4 ]- A layer of aluminum oxide previously formed by passive corrosion is dissolved by the addition of sodium hydroxide. For this reason, the reaction takes place at the beginning relatively slowly: Al2O3 + 2 NaOH + 3 H2O -- 2 Na+ + 2 [ Al(OH)4 ]- The aluminum completely dissolves and the water acts here too as an acid (for an analog, see Experiment 4.4.1). This reaction is used in drain cleaners. They are mostly made out of strong alkalis, to which alumunim or zinc has been added. The alkalis break down organic residues chemically. In addition, the formation of hydrogen leads to a bubbling effect which adds an additional mechanical cleaning mechanism. The big problem here is the formation of hydrogen gas (as well as some heat). The hydrogen gas is flammable, and if it's in a closed container, will explodes
I was told that Aluminum could not be sterilized, is this true?
- Sterilization refers to the ability to clean a surface of bacterium. Simply pouring rubbing alcohol on something sterilizes it. Aluminum can be sterilized just as good as any other metal. If it couldn't, would we ship our favorite drinks in cans of it?s
