Ascorbic Acid and Apple Cider Vinegar
I understood that there'd be occasions to use ascorbic acid in whole grain breads. I've been searching for a reasonable local source, but have found it to be questionably dear. When I researched online sources, I found that a crushed 250mg vitamin C tablet will do in place of 1/8 teaspoon ascorbic acid to a loaf of bread. Great, because I have a lot of vitamin C tablets otherwise going to waste.
I've also noticed quite a few recipes that I would be interested in making call for apple cider vinegar. Fortunately, before I actually bought any I checked my pantry and found I already had it. But I'm wondering if the vinegar serves the same function as the ascorbic acid. That is would I use one or the other but not both?
Assuming so, is there a chemist out there who can explain in lay terms why I might choose one over the other?
And I'm assuming that these are merely "nice" additives but not essential, that they improve gluten strength and allow for higher rising dough. Is this correct?

apple cider vinegar may contain trace amounts of vit. c but mainly it contains vinegar. Vinegar or ascetic acid is formed by the oxidation of ethanol (exposing drinking alcohol, wine et al, to air for some time). I know the chemistry, but as yet don't have the baking experience to answer the rest of your question. Hope that helps.

... If you don't find a local source.
Have you tried to call a Walgreens pharmacy ?

I found I don't need to buy ascorbic acid after all because I have the vitamin C tablets.
And vinegar and ascorbic acid are both acids. That's why I thought they might serve the same purpose. That's what I want to know about.
