A while ago I made a note of something Swede had posted about the rate of acid dosing. Adding 0.057 mL of 32% HCl per amp per hour with the HCl volume cut by 33% after crystals form seemed to be the ideal rate for him. Is this a good rule of thumb to go by? It's those numbers that also led to my believing that I wasn't adding enough HCl to my chlorate cell. I'm also wondering now, how susceptible is this rate to the cell temperature?
I believe it is, and a good starting point. Remember, if you dilute the acid, increase the volume by that same amount.
If you drop the acid to 8% (1/4 of full concentration), multiply the volume by 4 and see if that works for you.
