Discuss the mechanism of rusting of iron

WebRust is weaker, more brittle, and less dense than iron, so the formation of rust can negatively impact iron objects and structures. The chemical formula for rust is F e O H O 2 3 2 ⋅ 𝑛 . The formation of rust is a multi-step process wherein dissolved iron ions combine with water to make iron(III) hydroxide, which then dehydrates into rust. WebTinning: It is a process of coating base metal (iron) with tin (Sn). It can be carried out by hot dipping method. The iron sheet (base metal) first washed thoroughly with organic solvents to remove any organic matters. Then treated with dil. H2SO4, to remove rust and seal deposits, finally it is washed well with water and air-dried.
