A/B tek was used. Phosphoric acid rather than vinegar. NaOH was added, mimosa soup turned deep purple/black color. When sodium was added, the color changed to a bright pink and the mimosa seemed to clump up together. The volume had been reduced significantly, but the end solution wasn't thick or sludgy.
Any idea what's going on? When the pink solution is heated, it re-mixes with the rest of the mimosa and it turns normal purple/black.
Thanks.
