Hello, members of the List, A number of posts have indicated that calcium ascorbate can be expensive. I put a Vitamin C tablet next to a calcium carbonate antacid tablet in drinking glass, added enough distilled water to cover them, watched the reaction awhile, pulverized the tablets, stirred the mixture, and tasted the result.
The ascorbic acid tablet and calcium carbonate tablet produced bubbles where they touched underwater. I suppose the bubbles were carbon dioxide. The final product tasted bland and not unpleasant. I suppose it was calcium ascorbate solution. One thing I can say for sure is that it was not expensive. Best regards, Matthew
