Question

The net ionic equation for formation of an aqueous solution of nii2 accompanied by evolution of co2 gas via mixing solid nico3 and aqueous hydriodic acid is

Answer 1

Hey there!:

The balanced reaction is as follows

NiCO3(s) + 2HI(aq) ⇌ NiI2(aq) + CO2(g) + H2O(l)

The net ionic equation shows all the ions that react or change state. In this case, the only ion that does not change state is the I⁻ ion (in both reactant and product, it is aqueous).

Therefore the net ionic equation is:

NiCO3(s) + 2H⁺(aq) ⇌ Ni²⁺(aq) + CO2(g) + H2O(l)

Hope that helps!

Answer 2

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

Explanation:

Net ionic equation of any reaction does not include any spectator ions. These are the ions do not get involved in a chemical equation. It is also defined as the ions which are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of nickel carbonate and hydroiodic acid is given as:

$NiCO_3(s)+2HI(aq.)\rightarrow NiI_2(aq.)+CO_2(g)+H_2O(l)$

Ionic form of the above equation follows:

$NiCO_3(s)+2H^+(aq.)+2I^-(aq.)\rightarrow Ni^{2+}(aq.)+2I^-(aq.)+CO_2(g)+H_2O(l)$

As, iodide ions are present on both the sides of the reaction, thus, it will not be present in the net ionic equation.

The net ionic equation for the above reaction follows:

$NiCO_3(s)+2H^+(aq.)\rightarrow Ni^{2+}(aq.)+CO_2(g)+H_2O(l)$
