Question

. (a) Explain the oxidation states of halogens.
(b) (i) Formulate a cell from the following electrode reactions :
+ 3e─ Au(s)
Mg(s) + 2e─
(ii) Explain the variation in atomic or ionic radii of 3d – series elements.​

Answer 1

Explanation:

a)All halogens possess the oxidation state 0 in their diatomic forms. Fluorine exhibits the oxidation states of −1 (F− ion) and +1 (hypofluorous acid). The principal oxidation states of chlorine, bromine, and iodine are −1, +1, +3, +5, and +7. The oxyacids are compounds in which halogen atoms are joined to oxygen atoms.
