The decrease took so long because the free calcium carbonate in the soil was also dissolved by the acidification.
Bibby J. M., Hukins D.W. (1993) ' Acidification is not a feasible method for preventing encrustation of indwelling urinary catheters ' .
Conventional prevention and treatment of this problem involves acidification of the urine in order to prevent or dissolve the encrustation.
Cytosolic entry of bisphosphonate drugs requires acidification of vesicles after fluid-phase endocytosis.
It is a yellow amorphous powder which is soluble in dilute alkalis, the solution on acidification giving an hydroxide, C1 4 Mo 3 (OH) 2, which is soluble in nitric acid, and does not give a reaction with silver nitrate.
