Consult the table of standard electrode potentials given in the test and suggest three substances that can oxidise ferrous ions under suitable conditions?

Text Solution

Verified by Experts

Substances like `F_2, Cl_2, Br_2` which have more values of standard-reduction potentials than that of `Fe^3[0.77 ~V]` will be able,to oxidise `Fe^2 *` ions to `Fe^2+` ions.

    Hydrogen is the most abundant element in the universe, but in free state it is almost not found in earth's atmosphere. suggest any three methods for the preparation of H_2 gas by selecting suitable substance given below.

    If an element is in its highest possibel oxidation state in a compound, it can act as an oxidising agent. If an element is in its lowest possible oxidation state in a compound, if can act as reducing agent. If an element is in the intermediate oxidation state in a compound, it can serve as both oxidising and reducing agent. Based on the above three guidelines, classify the following compounds into three categories and post them in the table given below. KMnO_4 , H_2O_2 , H_2C_2O_4 , FeSO_4 , HCIO_4 , SO_2 , Na_2S_2O_3 , K_2Cr_2O_7
