Question

Calculate ΔG° and emf that can be obtained from the following cell under the standard

conditions at 25°C.

Zn(s)/Zn2+(aq)// Sn2+(aq)/Sn(s)

[Given, E°Zn2+/Zn = -0.76 V ; E°Sn2+/Sn = -0.14 V] and F = 96500 C.​

Answer 1

Explanation:

Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment. In its dense synthetic form, zinc sulfide can be transparent, and it is used as a window for visible optics and infrared optics.
