Chapter 8, Problem 8.83E

What is the estimated velocity for ${\text{Cu}}^{2+}$ ions moving through water in a Daniell cell in which the electric field is $\text{100}\text{.0}\text{V/m}$? Assume that $\stackrel{\circ }{\text{a}}$ for ${\text{Cu}}^{2+}$ is $4\stackrel{\circ }{\text{A}}$ and the viscosity of water is $0.00894\text{poise}$. Comment on the magnitude of your answer.
