How to measure corrosivity
Web7.4 Alkalinity. Alkalinity is a measure of the acid-neutralizing capacity of water and is usually determined by titration against sulfuric acid to the endpoint of the acid–base reaction. In groundwaters, the carbonate species predominate and an endpoint of about pH 4.5 marks the consumption of bicarbonate in solution. WebCorrosion compounds form on the surface of a solid material. If the compounds are hard and impenetrable, and if they adhere well to the parent material, the progress of …
