What you are given
- Mobility (µm·cm/V·s): 1.0
Formula: ζ = 3 η μ / (2 ε_r ε₀ f)
Physical
How do you calculate zeta potential?
Convert electrophoretic mobility to zeta potential (Henry / Smoluchowski / Huckel). The relationship used is ζ = 3 η μ / (2 ε_r ε₀ f).

The working
- Henry's factor:
f(κa)=1.5 - Mobility (SI):
μ=1.000e-8 m²/V·s - Zeta:
ζ = 3ημ / (2 ε_r ε₀ f)=12.8 mV
ζ = 12.8 mV
