Small amounts are chemically converted into carbonic ,acid, according to the following ,formula,. CO₂ + H₂O = H₂CO₃ If the ,pH, is greater than 9, carbonic ,acid, dissociates to produce two protons, which are released for neutralisation. Only one proton is produced if the ,pH, is less than 9. Although neutralisation

As the ,pH, value of the ,wastewater, increases beyond about 10, excess calcium ions will then react with the phosphate. Because the reaction is between the lime and the alkalinity of the ,wastewater,, the quantity required will be independent of the amount of phosphate present. It will depend primarily on the alkalinity of the ,wastewater,.

2.3. Determination of ,discharge, . River ,discharge, is the amount of water flowing in a channel or river per unit of time. The commonly applied method for determining river ,discharge, is the river profile method (cross section). In this method the ,discharge, is the product of multiplication between the vertical cross-sectional area of the river (river

It's used for pH compensation in water applications using a glass-electrode. The calculation is valid for all strong acids and strong bases. The main application is in de-mineralized water and alkalised boiler feed water/condensate. The uncompensated pH value is: pH uncomp = -log (c[H 3 O +]) => c[H 3 O +] = 10-pHuncomp. where:
