Question

(a)

No reaction occurs because reduction potential of silver is greater than that of copper, so it will not get oxidized to replace Cu2+.

(b)

No reaction occurs because reduction potential of copper is greater than that of magnesium, so it will not get oxidized to replace Mg2+.

(c)

The balanced reaction is:

Zn(s) + Pb(NO3)2 ---> Zn(NO3)2 + Pb(s)

(d)

The balanced reaction is:

Pb(s) + 2AgNO3 ---> Pb(NO3)2 + 2Ag(s)

(e)

No reaction occurs because both MgCl2 and NaCl are completely soluble, so no precipitate formation takes place.

Hope this helps !

Write the oxidation, reduction, and redox reactions for:

a) silver (Ag) reacting with Cu(NO3)2 (Why is it that no reaction occurs here?)

b) copper (Cu) reacting with Mg(NO3)2 (Why is it that no reaction occurs here?)

c) zinc (Zn) reacting with Pb(NO3)2

d) lead (Pb) reacting with AgNO3

e) magnesium (Mg) reacting with NaCl (Why is it that no reaction occurs here?)

Please show ALL steps and explanations. Thank you.
