Which of the following radicals will be precipitated by passing H_(2)S through a conc. HCI solution?
The organ of a person has been damaged completely due to a poisonous waste material B has started accumulation in his blood making it dirty In order to save this persons life the blood from an artery in the person s arm is made to flow Into Iong tubes made of substance E which are kept in coiled form in a tank containing solution F . This solution contains three materials G H and I similar proportions to those in normal blood As the person s blood passes through long tubes of substance E most of the wastes present in it go into solution The clean blood is then put back into a I In the person for circulation (d) What are G, H and I
