Leaching: Types, Methods, Advantages, Disadvantages

A soluble chemical is extracted from a solid matrix by this process. The solid matrix can be a body of ore, a mineral deposit, a formation that holds water, or a landfill. Metals like copper, or non-metals, like arsenic, can be soluble substances. A solvent, such as water, acid, or air, is passed through the solid matrix to achieve leaching.

Chemistry Explained: Iron

Iron in ground waters is normally present in the ferrous (Fe2+), or soluble state, which oxidizes easily to ferric (Fe3+) iron on exposure to air. Iron can enter a water system from leaching of natural deposits, iron-bearing industrial wastes, effluents of pickling operations, or from acidic mine drainage. Iron in domestic water supply systems ...

Why, out of the main halogens, is bromine the most soluble in water?

This is where the well-known impact of an iodide salt comes in: iodine is much more soluble in water that contains iodide because the triiodide ion, $ce{I3^-}$, with its delocalized three-center four-electron bond, is formed in the solution. Such a behavior is not significantly carried over to any lighter halogens.
