We have recently become curious about the pH of carbonated water – the kind that only contains bubbles and flavor, but no extra sugar. In keeping with our natures, Ian & I have decided to run an experiment to find out. Here’s what we’re going to do.
Over time, as the carbonation in an open can of sparkling water escapes, the acidity of the beverage will move from more acidic towards more neutral.
