How come after soda water loses its carbonation, it appears to have a salty/weird taste?
In: Chemistry
As someone who carbonates water at home, the addition of co2 slightly affects ph. So this maybe be what you are tasting.
> Natural and manufactured carbonated waters may contain a small amount of sodium chloride, sodium citrate, sodium bicarbonate, potassium bicarbonate, potassium citrate, potassium sulfate, or disodium phosphate, depending on the product.
Those compounds are different kinds of salts.

There are various natural and artificial flavors in soda and many of them are subject to oxidation. High pressure CO2 leaves little room for dissolved O2, so as CO2 pressure drops more O2 is able to dissolve into the soda. The natural and artificial flavors start to break down as they react with oxygen. This makes the soda taste different and since some of the flavoring was broken down the salt already in soda becomes more noticeable
The dissolved carbon dioxide leaves behind carbonic acid in the water when it goes out. That’s what you’re tasting, the effect the carbon dioxide had on the water.
When you carbonate water, some of the CO2 gas turns into cabonic acid. Most of the carbonic acid turns back into CO2 and water, but some of it stays in solution, so flat soda tastes of very weak carbonic acid.
If you are drinking natural sparkling water, then that water comes from mineral springs which have all sorts of dissolved minerals and salts in them. Once dissolved gas is gone, you can still taste all the other stuff.
