Question about carbon dioxide

  1. Jun 8, 2012 #1
    If carbon dioxide is the gas we exhale and is not healthy to breathe back in, then howcome they put carbon dioxide gas in tonic water?!

    Taste and texture. You are drinking it, not breathing it. But if you try to breathe your tonic water, the CO2 content will be the least of your worries!
