So, I got some grade 5 titanium in finally.
I put in in my cell as the anode expecting to see a lot of chlorine coming off it, and there was none. Instead it sloughed off some off-white flakes of stuff. I'm guessing it is titanium dioxide. I don't know what else it would be.
My guess is that titanium chloride wants to form; but because there is water right there, it forms into titanium chloride and hydrogen chloride instead.
Although no fumes of HCl are coming off.. unless its immediately getting absorbed into the water. I'll let it go for a while to see if HCl will eventually come off.
?? TiCl4 + 2H2O -> TiO2 + 4HCl
Anyone know what is going on?
Anyone know of an anode material that will not degrade in a HCl electrolyte where Cl2 is supposed to be coming off the anode? The only thing I've found is carbon, which falls apart rather quickly and doesn't conduct electricity very well. (Something that is not insanely hard to acquire)
