this is where physics and chemistry meet. CO2 doews not dissolve well in water ( or watery solitions like beer) so adding something that dissolutes well 'drives' ot the CO2. Sugar in carbonated sodas, salt in beer that has gone flat( to bring up a head again - yuck!). Rem: unlike other substances that dissolve better in water when one heats it CO2 dissolves less well (IIRC actually with rising heat the chance of the H2CO3 breaking up into H2O and CO2 increases so that most carbonic acid is driven out. ) now I must go and find a user-icon appropriate for this kind of comment.
ah think
