Problem 96P

Determine whether each reaction is a redox reaction. For those reactions that are redox reactions, identify the substance being oxidized and the substance being reduced.

(a) Pb(NO3)2(aq) + 2 LiCl(aq) → PbCl2(s) + 2 LiNO3(aq)

(b) 2 HBr(aq) + Ca(OH)2(aq) → 2 H2O(l) + CaBr2(aq)

(c) 2 Al(s) + Fe2O3(s) → Al2O3(s) + 2 Fe(l)

(a) Na2O(s) + H2O(l) → 2 NaOH(aq)

Step-by-Step Solution:

Solution 96P :

Step 1:

Here, we have to determine whether each reaction is a redox reaction and identify the substance being oxidized and the substance being reduced for redox reactions :

We identify if the given reaction is redox reaction by looking at its oxidation numbers. If the oxidation numbers of the atoms in the reaction has changed then it’s a redox reaction. If the atom’s oxidation number increases then the atom is oxidized and if the atom’s oxidation number decreases then its reduced.

 

(a) Pb(NO3)2(aq) + 2 LiCl(aq) → PbCl2(s) + 2 LiNO3(aq) :

Let’s assign the oxidation numbers for the atoms here :

        Pb(NO3)2(aq) + 2 LiCl(aq) → PbCl2(s) + 2 LiNO3(aq)

         (+2) (-12)         (+1)( -1)    (+2)(-12)    (+1)( -1)

We know for a neutral atom, the sum of the oxidation numbers should be zero.

Here, in the equation : The oxidation number of NO3 is -1 and since there are 2 atoms of NO3, the oxidation number will be -2 and to counteract that Pb will have the oxidation number of +2. The oxidation number of Cl is -1 and to counteract that Li will have charge of +1. Similarly the oxidation numbers are for PbCl2 and LiNO3. Here, we see there were no change of oxidation numbers of atoms anywhere, Hence this is not a redox reaction.
