Question
Given the cell reaction,
Zn(s) + Cut2
Cu(s)
Cu +2
the cathode in the cell is:
O Pt
(aq)
Zn(s)
(aq)
Zn(aq)
→ Zn¹2 + Cu(s)
+2
(aq)
Transcribed Image Text:Given the cell reaction, Zn(s) + Cut2 Cu(s) Cu +2 the cathode in the cell is: O Pt (aq) Zn(s) (aq) Zn(aq) → Zn¹2 + Cu(s) +2 (aq)
The standard (half cell) reduction potentials of two reactions are given below.
Li+ (aq) + e
F2(g) + 2e¯
(aq)
From this information, one may conclude that Li(s):
Li(s)
2F
is an excellent reducing agent
is an excellent oxidizing agent
is very difficult to oxidize
will not react with F2(g)
is very electronegative
Eº = - 3.04 V
E° +2.87 V
