Well done Cody!

Very cool to watch Cody. Thank you for sharing with us.

I confess I'm curious about why you used an MHD pump. Because the electricity was sort "already there and in play"? Regardless, it's very interesting work!

I tried a centerfugal pump but the smallest one I could get just moved way too much mercury.

Neat little design. You probably could improve chlorine yield by reducing the resistance (roughing up the surface of the strip; bringing it closer to the surface of the mercury) and/or lowering the voltage, judging from the color of the gases you're getting a lot of oxygen formation.

When I was designing a prototype once to pump liquid I used a Peristaltic Pump. It was a roller and a silicone tube that pumped liquid. It was really useful as I was using it for food grade and didn't want any moving parts touching the liquid. I don't know if it would pump mercury though.

Keeping down that cup of HCl with that thing.. Seems like maybe better have a holder for tubes or clamp for tubes? .. i'm not a chemist, though..

Nice! Maybe you can figure out some way to vent the connecting tubes, in case you cannot avoid the gas building up in them.

A couple of thoughts on your setup: 1. you may want to increase the contact surface especially in the second flask (where NaOH gets generated) by using a larger container; 2. you may want to decrease the total amount of mercury in the system; 3. increase the flow rate of the mercury; the MHD pump is cool and I may steal your concept in a future project, yet I think you would benefit from an increased rate of elimination of sodium amalgam from the first flask by using e.g. a peristaltic pump; that would also allow you to reduce the length of the mercury return path. Also I'm not familiar with gallium-sodium alloy properties, would this work with gallium if it were kept at an appropriate temperature?

I'm sure it would if properly designed and dimensioned for the fluid you're moving. Especially since you're not pumping against a height gradient.

I agree on all your points and I may rebuild it again. The gallium won’t work since it reacts with sodium hydroxide. Though a gallium cell would still make chlorine.

Yeah I forgot that one must think of gallium as "liquid aluminum"

Also as I mentioned in a comment on YT make sure you don't let the chloride concentration in the first flask drop too low or your platinum anode will start dissolving.
