Club soda (original) (raw)

Club soda is a manufactured form of carbonated water, commonly used as a drink mixer. Sodium bicarbonate, potassium sulfate, potassium bicarbonate, potassium citrate, or sodium citrate is artificially added to replicate constituents commonly found in natural mineral waters and offset the acidity of introducing carbon dioxide gas (which creates low 3-4 ph carbonic acid when dissolved in water).
