pH Adjustment and Neutralization the basics
pH Adjustment and Neutralization the basics

In very simple terms bases are used to neutralize acids, while acids are used to neutralize alkalis (the term caustic, alkaline, alkali, or base, although not truly synonymous, are often used interchangeably ). The byproducts are normally salts (which may or may not be soluble) and water. Neutralization Reactions

The ability of alkali metals to raise the pH when dissolved in water helps explain how the term “alkaline” has come to describe water whose pH is greater than 7. An alkaline solution simply means it has a pH greater than 7. Alkalinity, on the other hand, refers to a solution’s quantitative ability to neutralize an acid.

Alkalinity - Wikipedia
Alkalinity - Wikipedia

Although ,alkalinity, is primarily a term ,used, by oceanographers, it is also ,used, by hydrologists to describe temporary hardness. Moreover, measuring ,alkalinity, is important in determining a stream's ability ,to neutralize, acidic pollution from rainfall or ,wastewater,. It is one of the best measures of the sensitivity of the stream to ,acid, inputs.
