Sodium hydroxide is added to a cylinder of aluminum nitrate, precipitating out aluminum hydroxide. When additional base is added, the precipitate dissolves. The reactions can then be reversed with the ...

Sodium aluminate forms through the chemical reaction of aluminum oxide with sodium hydroxide and water, as follows: The residues sink gradually to the bottom of the tank and are later removed. In the ...

Sodium hydroxide isn’t super safe, but it is much less problem to buy, store, and use than battery acid. Aluminum naturally forms an oxide layer on its surface when exposed to air. Anodizing in ...

A few drops of dilute sodium hydroxide solution react to form a white precipitate with aluminium ions, calcium ions and magnesium ions. However, if excess sodium hydroxide solution is added ...

[Isographer] has an idea: to transport the energy not as hydrogen but as metallic aluminium, and generate hydrogen by reaction with aqueous sodium hydroxide. He’s demonstrated it by generating ...
