Question

Mg also redds vigorously with add solutions. For example, the reaction of Mg with HCI solution, shown in Equation 5, involves the transfer of electrons from Mg to hydrogen ions (H^+), resulting in the formation of molecular hydrogen, H_2. Mg(s, silver) + 2 HCL(aq) rightarrow MgCl_2(aq) + H_2(g) (eq. 5) The vigor of the reaction is evidence of Mg's reducing strength. Based on this information and your observations of the Zn-HCl reaction in Part IV, which substance is the stronger reducing agent, Mg or Zn? briefly explain.

Explanation / Answer

Mg is a stronger reducing agent then Zn because:-

A) more metallic character and hence more tendency to loose electrons

B) lower ionisation energy

C) higher oxidation potential

D) more reactive towards acid to liberate Hydrogen
