Rust is a reddish-brown flaky coat present on the metal. Technically, rust is a Hydrated Iron (III) Oxide whose chemical formula is Fe2O3x H2O. The rusting of the iron formula is represented by 4Fe + 3O2+ 6H2O → 4Fe(OH)3. Rusting can be prevented by galvanization, painting, and...
Both the reactant and product sides of the above equation may contain multiple chemical compounds, so one might re-write it as, where the different capital letters are intended to represent different chemicals involved in the reaction which can be, in turn, made up of various types of atoms....

This equation shows that Fe(II) ion in the GR-II is more readily incorporated into the ferrites than Ni(II) ion.doi:10.1246/bcsj.59.1829Tamaura YutakaBulletin of the Chemical Society of Japan
But why add rock salt to the mix? Rock salt brings an abrasive texture to the equation. It gently scrubs away the broken-down rust particles without causing any harm to the tile surface. Here’s a simple step-by-step guide on how to use this dynamic duo: ...
Interestingly, applying the Scherrer equation to the first diffraction peak gave much smaller diameters for the minimum crystallite size (L, Table 1), of around $20 nm (6–40 nm). This could be the result of shape effects whereby the spherical shape parameter (k) in the Scherrer equation ...
By the above equation, the real-time bar corrosion rate can be obtained. As in Fig. 11, the corrosion rate of bar increases with the progress of concrete cracking. Bar corrosion dramatically speeds up after the concrete completely cracks. It indicates that concrete cracking has great impacts on...
