FCO2

Carbon dioxide is in gaseous form and its solubility in water is relatively high compared to other gases. Carbon dioxide enters aquatic ecosystems through respiration, surface diffusion, and the decomposition of organic matter. CO2 is essential for aquatic plants, helps maintain the water's pH balance, and influences calcium carbonate levels and nutrient availability.Principle of analysis:
When NaOH is added to a water sample, it reacts with free Co2 to form sodium bicarbonate. This reaction consumes a known amount of NaOH, leaving the remaining NaOH to be measured. Phenolphthalein is used as an indicator to detect the titration endpoint, changing color from pink to colorless as the NaOH is used up. The amount of free Co2 in the water can then be calculated based on the volume of NaOH consumed in the reaction.

Free Carbon Dioxide

A varied array of mathematical derivations from various titrimetric and colorimetric methods for analyzing water quality parameters were condensed and integrated for the better physicochemical analysis. It is indispensable for managing any aquatic ecosystem, including aquaculture facilities. By substituting titrant and spectrophotometric absorbance readings, accurate determination of the concentrations of critical parameters such as Dissolved Oxygen, Free Carbon Dioxide, Total Alkalinity, Water Hardness, Hydrogen Sulfide, Total Ammonia Nitrogen, Nitrite, Nitrate, Chlorinity, Salinity, Inorganic Phosphate, and Transparency can be facilitated APHA(2017,ISBN:9780875532875).
