What happened when citric acid and and bicarbonate soda mixed together

The reaction follows the normal rules for an acid-carbonate reaction, which in turn is a special kind of acid-base reaction.

Acid + Carbonate -> Salt + Water + CO2

(Citric Acid) + (bicarbonate soda) -> (Trisodium citrate) + water + CO2

This is a very fast reaction, which produces a lot of carbon dixoide in a very short amount of time, which is the bubbles that you see. The other chemicals produce are clear liquids, so you don't see any of them.

1.from liquid state to gaseous state is evaporation 3.solid to liquid is melting 5. solid to gaseous state is sublimation 6. gas to solid state is decomposition 7. a change of state is known as the states of matters
