Are the following Redox reactions or non-Redox reactions? If you
determine that they are Redox, state which reactants have been
Oxidised and which have been Reduced?
Also remember to assign oxidation numbers for all atoms or
ions on the reactant and product side to denote electron
transfer for reactions identified as Redox.
i) Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s)
ii) NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)
iii) Al(s) + Cu2+ (aq) → Al3+
(aq) + Cu(s)
iv) Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
v) CaCO3(s) → CaO(s) + CO2(g)
