How come there aren’t any tablets to make sparkling drinking water (the Soda Stream way), although there are tablets that can make the it sparkling, i.e. water soluble Vitamin C tablets?

Question

I have really searched all over the internet, it doesn’t exist. I believe I can’t be the first one to think of that trick, so there must be a reason for that. Can anyone illuminate me by explaining like I’m really 5, as I’m a chemistry alien. Thanks!

Answer 1

The gas needs to be contained while it escapes from the pellet, which forces it into dissolving in the liquid. You see Co2 bubbles in carbonated liquid because the carbon is escaping. Water carbonators require the bottle to be sealed so that the co2 is able to dissolve into the liquid. If you just put a tablet it water all the co2 will escape into the air
