A person's immune system produces antibodies against any antigens not found in his blood.
Before giving a blood transfusion, it is necessary to determine the blood type of the recipient and that of the donor so that blood can be appropriately matched. This is called blood typing. This helps prevent ABO incompatibility which might lead to several fatal symptoms and reactions. These include;
Fever and chills
Abdominal, back and chest pains
Jaundice
Nausea
Muscle pains
Systemic shock and organ failure.
The best way to determine the presence of halogens is by adding a silver nitrate solution to the solvent. This is because all halogens, except for fluorine, produce a precipitate with silver nitrate solution.Chlorine produces a white precipitate, bromine produces a pale cream colored precipitate and iodine produces a yellow colored precipitate.
If further testing is required, concentrated sulfuric acid may be added. The sulfuric acid will produce misty fumes with fluorine and chlorine, brown fumes with bromine and purple fumes with iodine.
hope this helped :)
