Carbonated water is incredibly common, and, in one form or another, just about everyone drinks it. Sometimes it is enjoyed alone, but often it is mixed with flavoring ingredients. Just about all soft drinks are flavored carbonated water, and in a sense beer, ale, champagne, and spumati are as well, except the traditional carbonation method for the alcoholic drinks is different from that of carbonated water.
Carbonated water with no other ingredients is usually called seltzer in the United States, whilst carbonated water with some added minerals is usually referred to as club soda. Please join me in looking at the history of this material and its unlikely contribution to modern chemistry.
