Question

A galvanic cell consists of a metallic zinc plate immersed in 0.1m zinc nitrate solution

Answer 1

Answer:

A galvanic cell consists of a metallic zinc plate immersed in 0.1 M Zn(NO3)2 solution and metallic plate of lead in 0.02 M Pb(NO3)2 solution. Calculate the emf of the cell. Write the chemical equation for the electrode reactions and represent the cell. (Given : E°Zn2+/Zn = -0.76 V; E°Pb2+/Pb = -0.13 V)Read more on Sarthaks.com - https://www.sarthaks.com/197210/galvanic-cell-consists-of-metallic-zinc-plate-immersed-in-1-m-zn-no3-solution-and-metallic

Answer 2

Explanation:

Anode reaction = Zn(s) → 2Zn2+(aq) + 2e-  According to Nernst equation
