Oxygen reacts at cathode (depolarisation) and oxidizes the ferrous iron to ferric hydroxide (rust). O 2 + 2H 2 O + 4e-==> 4OH- 4 Fe (OH) 2 + O 2 + 2H 2 0 ==> 4Fe(OH) 3 Flow rate is an important factor in CO 2 water corrosion. Bottom Line: if you want to make soft water from hard water (e.g. to brew a Pilsener), dilution with distilled water is the best route.

The current recommended levels of iron in well water varies slightly by state, but they range between .2 and 1 mg/l. When iron exceeds these levels, the taste and color of the water can be affected, giving water a metallic flavor or odor and a red, brown or yellow cast that can stain ral water supply, including well water.
