making carbonic acid

rocketsurgeon - 22-6-2013 at 19:44

Can anyone tell me a good process to make carbonic acid
without dry ice/ gas cylinders

By the way I only have basic lab ware with rubber stoppers, i am a beginning chemist.


Thank you :)

Please tell me this is just a pathetic <a href="https://en.wikipedia.org/wiki/Troll_(Internet)" target="_blank">troll</a> <img src="../scipics/_wiki.png" /> attempt.

When carbon dioxide dissolves in water it exists in chemical equilibrium producing carbonic acid: <img src="../scipics/_wiki.png" />

Pour yourself a glass of water. Done.

Lol who uses carbonic acid nowadays my dear friend... it's all about dihydrogen monoxide lately. No student should be without extensive knowledge on dihydrogen monoxide. It's a dangerous compound my boy, try the synthesis but please stay safe.

Why not spoonfeed? Here's a good setup:
1) Gas generating apparatus. This can be as simple as a milk jug with a straw in the top, hot glued to prevent gas escaping.
2) Beaker of water.
3) Place a bunch of baking soda and vinegar in the milk jug/whatever, close it up quickly and tightly, and lead the straw/hose/what-have-you through a container of water.
4) Wait until no more gas is produced.
5) Take the hose out of the container of liquid. This liquid should now be weak carbonic acid - and that's the best you can do.

ALTERNATIVE:
1) Buy some tonic water - it's probably a dollar or two where you live.

<a href="http://en.wikipedia.org/wiki/Tonic_water" target="_blank">Tonic water</a> <img src="../scipics/_wiki.png" /> tends to contain <a href="http://en.wikipedia.org/wiki/Quinine" target="_blank">quinine</a> <img src="../scipics/_wiki.png" /> and <a href="http://en.wikipedia.org/wiki/Sucrose" target="_blank">sucrose</a> <img src="../scipics/_wiki.png" /> (or another sweetener).

Perhaps you're thinking of <a href="http://en.wikipedia.org/wiki/Carbonated_water" target="_blank">club soda</a> <img src="../scipics/_wiki.png" />?

[edit] (I expend way too much effort on these posts. This took me more than two minutes, for only two short sentences!)

i must say i LOL'd over that reply

the none the less i have once back in time suggested making the bottle having a hose from the top going down below the bottle so the CO2 that wouldnt react with the water would become re-used
pressure would probably increase, making it more efficient as it would increase

perhaps just a CO2 cartridge for airsoft, popped underwater?
as of what i understand the higher pressure the CO2 is with the more efficiently the H2CO3 will bind to the water, or what you might want to call it.. (:

Thank you

Thank most of you for good replies. :)

a special thanks to elementcollector1 / antiswat.

Like I said I am a beginning chemist not a troll.
