It depends on the voltage. At 30 volts or less, switching every 30 seconds should probably be a minimum. It also depends on stirring, if you stir, then the switch rate can be increased significantly. The problem is that at low voltages, and if there is no stirring, then the ions that leave the anode, will simply get sucked back to the anode upon polarity reversal. > > > One puzzling aspect is that the appearance of the CS seems to be the > same as for the really concentrated stuff, bright red to transmitted > light, but so dark that it appears gray unless a bright light is shined > through.

The color will come from particles. Orange or red would be larger particles than most cs. The strong tyndall also supports this. As the particles increase in size you get the following colors: clear yellow gold orange red violet blue green clear (but milky due to the high tyndall) Tyndall goes up to the 3rd or 4th power of particle size if I remember right, so larger particles give much stronger tyndall.
