Kudos to Master Kephra.
The 250 ml/gold chloride/soda ash/Karo recipe works great! Thank you. Every time, forever and ever again.
My distilled water has a pH of 8.1 to begin with. With 6 drop of soda ash the pH goes to 8.8.
Just as triturating the amount of citrate in the Turkevich method affects particle size, pH can too, so I have been titrating my drops of soda ash to obtain a pH closer to 7.0. I understand that the reaction requires alkaline environment, but I am trying to reduce the alkalinity as my feces have a yellowish color associated with faulty fats digestion. The high alkality may be affecting my stomach acid level , which then affects the response by my gall bladder and pancreas, which is alkaline to neutralize the stomach acid. Without that strong acid signal, my gall bladder and pancreas may not be stimulated to secrete their juices as much.
Basically am reducing number of drops of soda ash to find the lowest pH that allows for the reaction, for my ingredients. If I started with neutral water, 6 drops would probably be okay, but with a pH of 8.1, I don't need as much alkality added.
It's a work in progress.
Am trying some CarboGain, but Karo is easier since it is already a liquid.
