I'll be use the Formula III to produce colloidal gold
When i prepare the solution for the process PH seems to low, how can i raise the PH of the solution safely.
1- I know sodium carbonate to raises PH but can i use it in this formula, if so, what is the amounts for a liter. And is there anything i have to do extra or be careful?
2- And if it's possible to use sodium carbonate, is it applicable to other colloidal gold formulas, and the amounts information will be useful.
3- Is there a maximum value for PH?
