WebApr 28, 2016 · Phosphate buffer involves in the ionization of H 2 PO 4– to HPO 4-2 and vice versa. Therefore, we will use the acidity constant K2 to determine the pK a value. Since pK1 is a negative logarithm of the acidity constant, pK a will be log (K2) or log (6.2*10 -8) or 7.21. To know more about the dissociation constants of weak acids and bases ... WebThe solubility of phosphate minerals is very dependent upon soil pH. The soil pH for optimum phosphorus availability is 6.5 ; At high or neutral pH, phosphate reacts with calcium to form minerals, such as apatite. Under acidic conditions, phosphorus may react with aluminum and iron to form minerals, such as strengite and varescite.
