Question $2$

Particles of $CuC{l}_2$ with an average diameter of $0\mathrm{.}3m$ were dispersed in methanol to give an ion

concentration about $6^{**}{10}^{-9}M$ and an electrophoretic mobility of $0\mathrm{.}35{10}^2{m}^2{s}^{-1}{V}^{-1}$ at $25C.$

Calculate electrical double layer thickness for this solution. Which limiting form of

electrophoretic mobility equation is most applicable in this system? What is the zeta potential

for these particles? Comment on the stability of solution.

For methanol, ${}_r=32\mathrm{.}7$ and $=0\mathrm{.}0017k\frac{g}{m}.sec.$
