It can also be produced by using excess sodium hydroxide in the reaction.1 In medicine, sodium edetate is used a s chelating agent to remove heavy metal, such as lead or mercury, from the blood. It is used to lower blood levels of calcium, to control heart rhythm disturbances cased by a heart medication.2 In food industry, it is used as an additive in flume water for washing fruits and vegetables.
