Hydrogen, carbon and oxygen are the elements found in H2CO3
Carbonic acid H2CO3
Hydrogen carbonate is a compound, not an element, and it therefore has a formula, not a symbol: H2CO3.
H2CO3 = Carbonic acid It is made by dissolving Carbon dioxide into Water. H2O + CO2 ----> H2CO3
h2co3 (aq)--> co2+ h2o
CO2 and H2O combine to form H2CO3. There isn't any balancing to be done, really.
H2CO3 is not used as buffer.
H2CO3 is not used as buffer.
Mg + H2CO3 = MgCO3 + H2
Carbonic Acid
Acids, HNO3 (nitric acid) and H2CO3 (carbonic acid) are acids.
Ka= [h+][HCO3-]/[H2CO3]
