Question

What is the standard potential of cell, Ni | Ni²⁺ (1M) || Cu²⁺ (1 M) | Cu?

If E°Cu = 0.337 V and E°Ni = - 0.236 V.

विकल्प

• - 0.753 V

• - 0.136 V

• 0.101 V

• 0.573 V

Answer 1

0.573 V

Explanation:

`"E"_"cell"^circ = "E"_"cathode"^circ - "E"_"anode"^circ = "E"_"Cu"^circ - "E"_"Ni"^circ`

= 0.337 V - (- 0.236 V) = 0.573 V
