What is the formula for hydrogen carbonate?

What is the formula for hydrogen carbonate...?

  • If Hydrogen charge is -1 and Carbonate is -2, wouldn't the formula be H2CO3 ? But that would make it carbonic acid. If it matters, this is the result of calcium carbonate reacting with hydrochloric acid.

  • Answer:

    For the first part, you are right in what you said. Hydrogen carbonate is the nomenclature of the compound. But, Carbonic acid is chosen to be the common name. Usually things do get common names in Chemistry. For the second part, you are wrong. The reaction of CaCO3 with HCl is: 2 HCl + CaCO3 --> CaCl2 + CO2 + H2O.

forumula of hydrogen carbonate is h2co3 , however in a solid or gaseous stat. It is only carbonic acid when it is in aqueous, in other words dissolved in water. The same to HCl, which you call hydrochloric acid. However, HCL (g) gas is called hydrogen chloride, not hydrochloric acid. Hydrogen chloride dissolved in water forms hydrochloric acid. You get what i mean? and, commenting the above, HCO3 - Is NOT HYDROGEN CARBONATE, INSTEAD IT IS HYDROGEN CARBONATE ION. The Ion part is very important as hydrogen carbonate anion is completely different to the standard hydrogen carbonate And, calcium carbonate + HCL, the products are calcium chloride, water and carbondioxide, h2co3 is not a product

hydrogen carbonate ion (bicarbonate in common name) --> HCO3- carbonic acid --> H2CO3 they are conjugate acid & conjugate base each other. CO32− +2 H2O --> HCO3− + H2O + OH− -->H2CO3 +2 OH− HCO3- is the conjugate base of carbonic acid ( H2CO3) HCO3- is the conjugate acid of carbonate ion (CO32-) calcium carbonate reacting with hydrochloric acid CaCO3 + 2HCl --> CaCl2 + H2O + CO2

Hydrogen charge is +1 and Carbonate is -2 and hydrogen carbonate overall charge is -1, therefore the formula is (HCO3)^ -

You've got it, but the hydrogen charge is +1
