Question

Sodium carbonate + hydrochloric acid ionic equation

Answer 1

Word Equation: Hydrochloric acid + Sodium carbonate → Sodium chloride + Carbon dioxide + Water

Formula Equation: 2 HCl (aq) + Na2CO3 (aq) → 2 NaCl(aq) + CO2 (g) + H2O (l)

Ionic Equation: 2 H+ (aq) + CO32- (aq) → H2O (l) + CO2 (g)

Answer 2

Answer: The net ionic equation for the given reaction is written below.

Explanation:

Ionic equation is defined as the equation in which all the chemical species are written in ions. Solids, liquids and gases do not form ions. So, they remain as such.

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of sodium carbonate and hydrochloric acid is given as:

$Na_2CO_3(aq.)+2HCl(aq.)\rightarrow 2NaCl(aq.)+H_2O(l)+CO_2(g)$

Ionic form of the above equation follows:

$2Na^+(aq.)+CO_3^{2-}(aq.)+2H^+(aq.)+2Cl^-(aq.)\rightarrow 2Na^+(aq.)+2Cl^-(aq.)+H_2O(l)+CO_2(g)$

As, sodium and chloride ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

$2H^+(aq.)+CO_3^{2-}(aq.)\rightarrow CO_2(g)+H_2O(l)$

Hence, the net ionic equation for the given reaction is written above.
