Reaction between NaHCO3 + HCl,?

Question

Reaction between NaHCO3 + HCl,

The chemical equation is

NaHCO3 + HCl --> NaCl + H2O + CO2

The question is
What form do these products take in the solution?
(hint are they ions or compounds?)

Answer 1

NaCl is an ionic compound. It exists as solvated ions in aqueous solution. H2O of course is a covalent compound, and CO2 is also covalent. A lot of it will not stay in solution though, because it is a gas and will just bubble off.

Answer 2

This is a reaciton between an Acid and a Base, which is called neutralization reaction which produce salt and water and CO2 is given off as gas. It is also known as Acid Base Reaction.

NaHCO3 is a salt which consists of the ions Na+ and the bicarbonate anion, HCO3-. In aqueous solution, these ions are separated.

Furthermore the bicarbonate anion forms some hydroxide, which results in its solutions being mildly alkaline:

HCO3- → CO2 + OH-

NaHCO3 is obtained by the reaction of carbon dioxide with sodium hydroxide:

CO2 + NaOH → NaHCO3
It reacts further with NaOH to produce the related salt, sodium carbonate:

NaHCO3 + NaOH → Na2CO3 + H2O
These reactions are reversible. Treatment of sodium bicarbonate with an acid, releases carbon dioxide and water:

NaHCO3 (aq) + HCl(aq) ––> NaCl(aq) + H2O(l) + CO2 (g)
