Solubility of Silver Oxides vs pH
Copyright 2012 W. G. Peters (aka kephra)
Municipal water suppliers are required to meet standards for metals in the water, and the way they remove metals is by raising the pH of the water causing the metal ions to precipitate out.
Silver is very susceptible to high pH also. This graph shows that at a pH of 10, the solubility of Silver Hydroxide drops to only 8% of its normal valute, or a mere 1.6 ppm. This means that an overload of sodium carbonate or sodium hydroxide will be harmful to the colloidal silver generation process. However, it takes a lot of electrolyte to get to pH of 9, so it won't happen by accident using the procedures given on this forum.
It also shows another reason why the silver lungs guy is full of BS when he claims his machine makes pH 10 silver. The silver would have precipitated out!
