Lesson 12: Corrosion Control

In general, corrosion is the result of water with a low pH. Acidic waters have lots of H + ions in the water to react with the electrons at the hode, so corrosion is enhanced. In contrast, water with a higher pH (basic water) lowers the solubility of calcium carbonate so that the calcium carbonate is more likely to precipitate out as scale.
