Some compounds and also the Hydracids such as HCl, HI, HBr, … Web20 feb. 2015 · Alkali metals are very good reducing agents because of their great tendency to lose electrons. The reducing character increases from Na to Cs. However, Li is stronger reducing agent than Na due to greater hydration energy. Explanation: An element, which acts as a reducing agent, must have low ionization energy.

Iron (Fe) has been oxidized because the oxidation number increased. Iron is the reducing agent because it gave electrons to the oxygen (O 2). Oxygen (O 2) has been reduced because the oxidation number has decreased and is the oxidizing agent because it took electrons from iron (Fe).

(ii) With 3d 4 configuration, Cr 2+ acts as a reducing agent but Mn 3+ acts as an oxidising agent (Atomic masses, Cr = 24, Mn = 25) (iii) The actinoids exhibits a larger number of oxidation states than the corresponding lanthanoids. WebIn the above reaction, sodium, which is oxidised, acts as a reducing agent because it donates electrons to chlorine. Chlorine is reduced and acts as an oxidizing agent because it accepts electrons from sodium. The second example is as follows:-. Reaction : 2 Na ( s) + O 2 ( g) → Na + 2 O 2 - ( s) Oxidation state: 0 0 + 2 - 2.
