Pharmaceutical
Citric acid can chelate metal ions, buffer pH and impart flavor in the pharmaceutical industry. It can also be used as an external anticoagulant as it can prevent blood coagulation by lowering the concentration of calcium ions in blood through binding with calcium ions which will form a soluble complex but difficult to dissociate.
Industry uses
1. Water softener
Citric acid's ability to chelate metals makes it used as a water conditioner in the treatment of industrial water and drinking water. Like EDTA, it is a chelating agent that can bind metal ions, commonly calcium and magnesium in water and remove them from pipes, household appliances, and etc.
