Solubility increases with the decrease of pH and is similar to that of calcium phosphate secondary to pH = 6.0 and to that of calcium phosphate primary to pH = 4.0.
La solubilidad aumenta con disminución del pH y es similar a la del fosfato de calcio secundario a pH = 6.0 y a la del fosfato de calcio primario a pH = 4.0.
