Question

Which acid is present in soft drinks? Ascorbic acid or carbonic acid?

Answer 1

Carbonic acid and ascorbic acid are using in soft drinks

In detail
The three most common acids in soft drinks are citric, carbonic and phosphoric acids. Citric acid comes from citrus products and any soft drink with citrus flavoring will contain it. The chemical formula is H(3)C(6)H(5)O(7). Carbonic acid forms from dissolved carbon dioxide, which is present in almost all soft drinks. The chemical formula is simply a combination of water’s H(2)O and the CO(2) of carbon dioxide, which makes H(2)CO(3). Soft-drink makers often add phosphoric acid to colas to produce a sharp flavor and to slow the growth of mold and bacteria. Most of the acidity in colas comes from phosphoric acid, whose chemical formula is H(3)PO(4).

Ascorbic acid and its sodium, potassium, and calcium salts are commonly used as antioxident additives. These compounds are water-soluble and thus cannot protect fats from oxidation: For this purpose, the fat-soluble esters of ascorbic acid with long-chain fatty acids (ascorbyl palmitate or ascorbyl stearate) can be used as food antioxidants.(preservation purpose).
