For statements a) through d)use the following reaction:

Cu(s) + 2Ag+(aq) --> 2Ag(s) + Cu2+(aq)

a) Cu is the reducing agent

b) Ag+ is the reducing agent

c) Cu is oxidized

d) Ag+ is oxidized
e) HCl(g) + NH3(g) --> NH4Cl(s)is aredox reaction

f) Cr2O72-(aq) +2OH-(aq) -->2CrO42-(aq) +H2O(l)is a redox reaction


Which of the below statements a) through f) aretrue?

For statements a) through d)use the following reaction:

Cu(s) + 2Ag+(aq) --> 2Ag(s) + Cu2+(aq)

a) Cu is the reducing agent

b) Ag+ is the reducing agent

c) Cu is oxidized

d) Ag+ is oxidized
e) HCl(g) + NH3(g) --> NH4Cl(s)is aredox reaction

f) Cr2O72-(aq) +2OH-(aq) -->2CrO42-(aq) +H2O(l)is a redox reaction

Explanation / Answer

a) Cu is the reducing agent (TRUE: Cu is oxidisedso itself causing reduction of others) b) Ag+ is the reducing agent (FALSE:Ag+ is reduced so itself causing oxidation ofothers) c) Cu is oxidized (TRUE) d) Ag+ is oxidized (FALSE) THUS, the correct statements are (A) and (C) Hope this helps!
