Question

Consider the Daniell cell, for which the overall cell reaction is Zn(s)+Cu2+(aq)⇌Zn2+(aq)+Cu(s) The concentrations of CuSO4 and ZnSO4 are 2.20×10−3 m and 1.10×10−3 m , respectively.

Part A

Calculate E setting the activities of the ionic species equal to their molalities.
Express your answer to four significant figures and include the appropriate units.

E = ?

Part B

Calculate γ±,ZnSO4 for the half-cell solutions using the Debye-Huckel limiting law.
Express your answer using three significant figures.

γ±,ZnSO4 = ?

Part C

Calculate γ±,CuSO4 for the half-cell solutions using the Debye-Huckel limiting law.
Express your answer using three significant figures.

γ±,CuSO4 = ?

Part D

Calculate E using the mean ionic activity coefficients determined in part (b) and part (c).
Express your answer to four significant figures and include the appropriate units.

E = ?
