Four test tubed marked I,II,III and IV were taken 20 ml of Al_2(SO_4)_3 solution in water was poured in each of the test tube I, an iron nails was put in test tube II, copper turnings were put in test tube III and a clean aluminium strip was placed in test tube IV. No change was observed in any four any in the test tubes. the correct inference drawn is

Equal lenghts of magnesium ribbons are taken is test tubes a and b hydrochloric acid (HCl) is added to test tube a, while acetic acid (CH_3COOH) is added to test tube b. amount and concentration taken for both the acids are same. In which test tube wil the fizzing occur more vigorously and why?

When conc. H_2SO_4 was added to an unknown salt present in a test tube, a brown gas (A) was evolved. The gas intensified when copper turnings were also added into this test tube. On cooling the gas A changed into a colourless gas (B). Write the equations for the reactions involved.
