Question

3.Give an example each of oxidation and reduction reaction on the basis of electro negative and electropositive element.

Answer 1

• $$\begin{gathered} 2{\mathrm{FeCl}}_3\left(\mathrm{aq}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right)\to {\mathrm{FeCl}}_2\left(\mathrm{aq}\right)+2\mathrm{HCl}\left(\mathrm{aq}\right) \\ \mathrm{Ferric}\mathrm{chloride}\mathrm{Hydrogen}\mathrm{Ferrous}\mathrm{chloride}\mathrm{Hydrogen}\mathrm{chloride} \end{gathered}$$

• $$\begin{gathered} 2\mathrm{HgO}\left(\mathrm{s}\right)\to 2\mathrm{Hg}\left(\mathrm{l}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right) \\ \mathrm{Mercurric}\mathrm{oxide}\mathrm{Mercury}\mathrm{Oxygen} \end{gathered}$$
