Acidity and Alkalinity - wastewater treatment
Acidity and Alkalinity - wastewater treatment

Acidity is a measure of a solution’s capacity to react with a strong base (usually sodium hydroxide, NaOH) to a predetermined pH value. This measurement is based on the total ,acidic, constituent of a solution (strong and weak acids, hydolyzing salts, etc.) It is possible to have highly ,acidic, water but have moderate pH values.
