Vedclass · Answer

(A) Sodium oxalate,sodium citrate,and $EDTA$ (Ethylene diamine tetra acetic acid) are used as anticoagulants in laboratories and blood banks. These substances function by binding to $Ca^{++}$ ions,which are essential for the blood coagulation cascade. By removing free $Ca^{++}$ ions from the blood,they prevent the conversion of prothrombin to thrombin,thereby inhibiting clotting. These compounds are known as chelating agents.
