Question

when CO2 is bubbled into an aqueous solution of Na2CO3 the compound formed is
​

Answer 1

Answer:The Na2CO3 is of course dissociated into ions Na+(aq) and CO3-- , as also is the NaHCO3, as Na+ and HCO3-. You can look upon the CO2 as combining with the H2O to give carbonic acid H2CO3.

Explanation:

Answer 2

Answer:

The chemical 2NaHCO3 is produced when CO2 is bubbled into an aqueous solution of Na2CO3.

Explanation:

You get NaHCO3 by a chain reaction:

2 NaHCO3 = Na2CO3 + CO2 + H2O

Of course, Na2CO3 is decomposed into the ions Na+(aq) and CO3--, and NaHCO3 is dissociated into Na+ and HCO3-. You might think of CO2 interacting with H2O to produce carbonic acid, H2CO3.

What is NaHCO3?

The disodium salt of carbonic acid with alkalinizing properties is sodium carbonate. When sodium carbonate (NaHCO3) is dissolved in water, it produces carbonic acid and sodium.

Thus, the usual salt of a weak acid is sodium carbonate (Na2CO3) (carbonic acid, H2CO3).
