The catch is that H2CO3 (carbonic acid) molecules don't exist in aqueous solution, so it is questionable whether they actually every form in the first place. 2 Na + Cl 2 → 2 NaCl. Problem: Which of the following is an oxidation-reduction reaction?a) Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)b) Pb(C2H3O2)2(aq) + 2NaCl(aq) → PbCl2(s) + 2NaC2H3O2(aq)c) NaI(aq) + AgNO3(aq) → AgI(s) + NaNO3(aq)d) HCl(aq) + LiOH(aq) → LiCl (aq) + H2O(l)e) All of the above are oxidation-reduction reactions. As a result the molecularity of the reaction is 3. Mg Mg 2+ + 2 e- And, each O 2 molecule gains four electrons to form a pair of O 2-ions. Mg(s) + Cl_2(g) rarr MgCl_2(s) The metal loses electrons, and in forming Mg^(2+) it loses 2 electrons and is oxidized: Mg(s) rarr Mg^(2+) + 2e^- (i) And on the other hand chlorine is reduced to chloride ion by accepting electrons: Cl_2(g) +2e^(-) rarr 2Cl^(-) (ii) And (i) + (ii)= Mg(s) + Cl_2(g) rarr MgCl_2(s) Both charge and mass are balanced, as required.
