I see what you're saying, but actually when you electrolyse water you get H+ and OH- ions, so it does have the possibility of playing with pH. Obviously, the ions should recombine as quickly as they are split, however, this is the way a lot of the alkaline water machines do their job. They use a semi-permeable membrane that keeps the alkaline and acid water seperated, the acid forming at the positive cathode and the alkali and the negative (or the other way around!)
I tested the pH of the mix before and after sonification, nothing else was done to it, no additions of water or anything else. The only change would be a slight increase in temperature I noticed, presumably from the US energy input. Before starting, pH was 3.5 after 40 mins of 70W 42khz bombardment the pH had dropped to 3.2. Not a lot, but it's about a 10% drop!
The bicarb test is supposed to assess the amount of encapsulation by the amount of foam that is formed when the bicarb solution meets the acidic lipo-C. Megamind got almost no reaction and about 1/16th inch of foam. Mine fizzed up and almost out the top of the glass. We are using the same Lecithin, both using pure powdered AA and both have a very similar looking mix.

A difference of 0.3 pH units says to me that it's fluctuation in whatever equipment you're using. Also, you have to realise that vitamin C is a weak acid, not a strong acid. It doesn't fully dissociate the acidic H+ in solution, but instead exists in equilibrium between it's protonated (acidic) and deprotonated (conjugate base) form. If it's not variation in your equipment, what it might be is simply the sonication pushing the equilibrium to the right, which would cause for there to be more H+ in solution, giving it a lower pH. Did you observe the same change using your lower power machine?

When you add bicarb to acid, you produce carbonic acid, which then breaks down to release CO2 gas and water. The CO2 is what's causing the bubbles you observe and how violent that reaction is depends on a bunch of things. The test seems a little pointless to me, though. Bicarb should react in the same way with plain old ascorbic acid as it would with the combination.

Has anyone thought of taking a look at this stuff through a microscope? Would you be able to see the bubbles and encapsulation?
Just a thought.

My solution was to mix a small amount of skim milk and a half a spoon of local raw honey. The honey completely overpowers the bad taste and makes it much easier to take. I hope that helps someone out there who is thinking of not taking this because of the taste.

Yes but I wouldn't expect the ph to change very much in a 16oz solution with an acid mixed with water in concentrations of 25% to 50%. I could be wrong but it doesn't seem to me that it would. I would have thought the strength of the acid would affect ph more - like battery acid vs lemon juice.
You obviously are more expert at this than I could you explain? Am I wrong in my assumption?
Also with the bicarb test. Wouldn't the amount of acid in the solution affect the reaction with the bicarb. The reaction would be biggest when the amount of acid and bicarb were equal in quantity (all of both reacting). And if there were less acid then less of an observed reaction - since not all the bicarb could react?

That's good to know - but I don't mind the taste at all. I think its actually kind of good. I could just sit around drinking it I think. My gf thinks I'm kind of nuts
