Question

The emf of a galvanic cell, with electrode potential of zinc $=+0.76\,V$ and that of copper $=0.34\,V$ , is:

• A. 0.76 V
• B. 1.1 V
• C. -1,1 V
• D. 1.6 V

Answer 1

Answer: (B)

1.1 V

Answer 2

The emf of a galvanic cell = electrote potential of zinc - electrode potential of copper $=0.76-(-0.34)=1.1\, V$
