I understand from reading here that 1Mol of Na2CO3 per Liter, and then one milliliter of this strength (say, 20drops) is the ideal amount of electrolyte to add to one Liter of DW to begin electrolysis of a batch of colloidal silver.

My question is, How was that strength determined? Is it based on the further claim that this gives a pH of 8.5 which is also claimed optimal?

If so, how is that determined?

I am not questioning the verity of these statements at all, just wondering how they were arrived at. Is it experiential or based on calculations?

Thank you in advance,
