So when you open a new bottle of sparkling water (or soda) it's very fizzy and aerated. However, when it is stored for quite a bit (no matter how tightly you close the bottle cap) it loses some gases and when you drink it later it's not as fizzy as it was before.
From my chemistry class I remember that sparkling water is basically a carbonic acid (H2CO3) that is constantly decomposing, producing water (H2O) and carbon dioxide (CO2). Then carbon dioxide escapes through the bottle cap little by little (but since it is heavier than air and hence is not rising upwards, I assume it escapes when having bottle opened due to pressure built up inside).
The question is: what if the bottle was stored upside down (so there is no way for gas to escape through the bottle cap), and shaken thoroughly before opened, so that carbon dioxide dissolved in water, like so
I also thought that it could be even better if the volume of the bottle was decreased (leaving enough volume for sparkling water only) like so Therefore carbon dioxide doesn't have enough volume to spread inside the bottle and most of it will stay dissolved in water.
Could anyone explain whether this will work or not?
