Neutral Solution: Definition & Examples - Study.com

WebIn aerated neutral or alkaline solutions the cathodic corrosion process is usually the reduction of oxygen. The kinetics of this cathodic process are controlled by the rate at which oxygen can diffuse to the surface of the metal, which is slower than the rate of consumption of oxygen by the cathodic reaction. Sulfur compounds dissolved in water are not necessarily dangerous, but can give the water a bad taste or foul smell. These compounds can be removed in several ways, the most effective being by exposure to chlorine gas. However, aeration can also be effective if the amount of sulfur in the water is relatively low. During aeration, water is pumped into a non-pressurized tank and agitated. T…
