10 Common Types of Corrosion - ThoughtCo

Pitting: Pitting results when a small hole, or cavity, forms in the metal, usually as a result of de-passivation of a small area. This area becomes anodic, while part of the remaining metal becomes cathodic, producing a localized galvanic reaction.The deterioration of this small area penetrates the metal and can lead to failure.

For instance, human blood is basic with a pH between 7.3 and 7.5. • If the blood pH drops < 7.3, acidosis occurs (diabetes). • If blood pH rises > 7.5, alkalosis occurs (Tums OD). • Below 7.0 and above 7,8, death occurs • One unit in pH equals a 10x change in acidity.

And if amounts of reagent are precisely adjusted, the water's alkalinity will be reduced to the theoretical solubility applicable to the CaCO 3 + Mg (OH) 2 system which ranges from 2 to 3°F under normal temperature and concentration conditions.. However, this limit M-alk. figure may be increased in practice when dissolved impurities are present (e.g. organic acids, ammonium, phosphates, etc.).
