Inhalation exposure to 100 mg/hr aluminium, in the form of powder, or 92 mg Al/ per 2 hr, as a fume, each day for 9-13 months showed a significant retention of aluminium in the lungs of both groups of animals. The aluminium retention in the lungs in rats and hamsters exposed to fume was much greater than when exposed to powder. Following exposure to fresh air, aluminium oxide was cleared

7. Could you store 500 ml Zinc sulphate solution in an aluminum vessel overnight? Give reason for your answer. Ans: Aluminium is more reactive than zinc therefore displace zinc from Zinc sulphate solution and form salt with evolution of hydrogen gas. This is why we do not store Zinc sulphate solution in an aluminum vessel overnight. 8

Explanation: Zinc is more reactive than copper.Thus, it is more electropositive than copper, meaning that zinc loses electrons more easily than copper. As a result, oxidation occurs at the zinc rod (the anode) and zinc metal loses electrons to become zinc ions, that is, Zn (s) - 2e--- Zn 2+ (aq) The electrons then flow from the zinc rod to the copper rod through the external circuit
