in each of the following reactions, identify the reactant that is oxidized and the reactant that is reduced.

A.) Ba(s)+Cl2(g)->BaCl2(s)

B.) Br2(g)+2KCl(aq)->2KBr(aq)+I2(s)

C.) 2Al(s)+3Sn^2+(aq)->2Al^3+(aq)+3Sn(s)

D.) Fe(s)+Pb(NO3)2(aq)->Fe(NO3)2(aq)+Pb(s)

Solutions

Expert Solution

In any redox reaction,first find oxidation number of each reactant present in the reaction and compare its oxidation number with its product side.

if there is increase in oxidation number of any element during a reaction,this means that element in oxidised

Similarly,if decrease in oxidation number occurs of any element,this means that element is reduced
