Can alkalinity be higher than hardness
WebThe alkalinity of a solution may be defined as the capacity it has for solutes to react with and neutralize acid [51].The total alkalinity includes all the bases that are titratable with strong acid. It is a measure of the buffering capacity of water, meaning that waters of low alkalinity will be very sensitive to pH changes, while those with high alkalinity content … WebNov 17, 2024 · At higher pH, the HCO 3-dissociates to yield H + and a carbonate ion (CO 3 =) (Equation 4).
