Answer from: SumayahAminaAnsari

Answer 1 : The balanced complete ionic equation will be,

$NaOH(aq)+HNO_3(aq)\rightarrow H_2O(l)+NaNO_3(aq)$

$Na^+(aq)+OH^-(aq)+H^+(aq)+NO_3^-(aq)\rightarrow H_2O(l)+Na^+(aq)+NO_3^-(aq)$

By removing the spectator ion in this equation, we get the balanced ionic equation.

$OH^-(aq)+H^+(aq)\rightarrow H_2O(l)$

Answer 2 : The balanced net ionic equation will be,

$2Na_3PO_4(aq)+3NiCl_2(aq)\rightarrow Ni_3(PO_4)_2(s)+6NaCl(aq)$

$6Na^+(aq)+2PO_4^{3-}(aq)+3Ni^+(aq)+6Cl^-(aq)\rightarrow Ni_3(PO_4)_2(s)+6Na^+(aq)+6Cl^-(aq)$

By removing the spectator ion in this equation, we get the balanced ionic equation.

$2PO_4^{3-}(aq)+3Ni^+(aq)\rightarrow Ni_3(PO_4)_2(s)$

Answer 3 : The balanced net ionic equation will be,

$2Na_3PO_4(aq)+3NiCl_2(aq)\rightarrow Ni_3(PO_4)_2(s)+6NaCl(aq)$

$6Na^+(aq)+2PO_4^{3-}(aq)+3Ni^+(aq)+6Cl^-(aq)\rightarrow Ni_3(PO_4)_2(s)+6Na^+(aq)+6Cl^-(aq)$

By removing the spectator ion in this equation, we get the balanced ionic equation.

$2PO_4^{3-}(aq)+3Ni^+(aq)\rightarrow Ni_3(PO_4)_2(s)$

Balanced equations : Balanced equations are the equations in which the number of individual elements present on the reactant side must be equal to the number of individual elements present on the product side.

Spectator ions : It is defined as the ions which do not participate in the chemical reaction. These ions exists in the same form on both the sides of the reaction.

Answer from: kalbaugh

The complete ionic equation for reaction 1 is as follows:

${\text{N}}{{\text{a}}^+}\left({aq}\right)+{\text{O}}{{\text{H}}^-}\left({aq}\right)+{{\text{H}}^+}\left({aq}\right)+{\text{NO}}_3^-\left({aq}\right)\to{\text{N}}{{\text{a}}^+}\left({aq}\right)+{\text{NO}}_3^-\left({aq}\right)+{{\text{H}}_2}{\text{O}}\left(l\right)$

The net ionic equation for reaction 2 is as follows:

$2{\text{PO}}_4^{3-}\left({aq}\right)+3{\text{N}}{{\text{i}}^{2+}}\left({aq}\right)\to{\text{N}}{{\text{i}}_3}{\left({{\text{P}}{{\text{O}}_4}}\right)_2}\left(s\right)$

The complete ionic equation for the reaction 3 is as follows:

${\text{6N}}{{\text{a}}^+}\left({aq}\right)+2{\text{PO}}_4^{3-}\left({aq}\right)+3{\text{N}}{{\text{i}}^{2+}}\left({aq}\right)+6{\text{C}}{{\text{l}}^-}\left({aq}\right)\to{\text{N}}{{\text{i}}_3}{\left({{\text{P}}{{\text{O}}_4}}\right)_2}\left(s\right)+{\text{6N}}{{\text{a}}^+}\left({aq}\right)+6{\text{C}}{{\text{l}}^-}\left({aq}\right)$

Further Explanation:

The three types of equations that are used to represent the chemical reaction are as follows:

1. Molecular equation

2. Total ionic equation

3. Net ionic equation

The reactants and products remain in undissociated form in molecular equation. In the case of total ionic equation or complete ionic equation, all the ions that are dissociated and present in the reaction mixture are represented while in the case of net or overall ionic equation only the useful ions that participate in the reaction are represented.

A) Steps to write the complete ionic equation of reaction 1 is as follows:

Step 1: Write the molecular equation for the reaction with the phases in the bracket.

In the reaction, ${\text{NaOH}}$ reacts with ${\text{HN}}{{\text{O}}_3}$ to form ${\text{NaN}}{{\text{O}}_3}$ and ${{\text{H}}_{\text{2}}}{\text{O}}$ . The balanced molecular equation of the reaction is as follows:

${\text{NaOH}}\left({aq}\right)+{\text{HN}}{{\text{O}}_3}\left({aq}\right)\to{\text{NaN}}{{\text{O}}_3}\left({aq}\right)+{{\text{H}}_2}{\text{O}}\left(l\right)$

Step 2: Dissociate all the compounds with the aqueous phase to write the total ionic equation. The compounds with solid and liquid phase remain same.

The complete ionic equation for reaction 1 is as follows:

B) Steps to write the net ionic equation for the reaction 2 is as follows:

Step 1: Write the molecular equation for the reaction with the phases in the bracket.

In the reaction, ${\text{N}}{{\text{a}}_3}{\text{P}}{{\text{O}}_4}$ reacts with ${\text{NiC}}{{\text{l}}_2}$ to form ${\text{N}}{{\text{i}}_3}{\left( {{\text{P}}{{\text{O}}_4}} \right)_2}$ and ${\text{NaCl}}$ . The balanced molecular equation of the reaction is as follows:

${\text{2N}}{{\text{a}}_3}{\text{P}}{{\text{O}}_4}\left({aq}\right)+3{\text{NiC}}{{\text{l}}_2}\left( {aq}\right)\to{\text{N}}{{\text{i}}_3}{\left({{\text{P}}{{\text{O}}_4}}\right)_2}\left(s\right)+6{\text{NaCl}}\left({aq}\right)$

Step 2: Dissociate all the compounds with the aqueous phase to write the total ionic equation. The compounds with solid and liquid phase remain same.

The complete ionic equation for the reaction 2 is as follows:

Step 3: The common ions on both the sides of the reaction get cancelled out to get the net ionic equation.

The net ionic equation for reaction 2 is as follows:

$2{\text{PO}}_4^{3-}\left({aq}\right)+3{\text{N}}{{\text{i}}^{2+}}\left({aq}\right)\to{\text{N}}{{\text{i}}_3}{\left({{\text{P}}{{\text{O}}_4}}\right)_2}\left(s\right)$

C) Steps to write the complete ionic equation for the reaction 3 is as follows:

The reaction 3 is same as the reaction 2 and therefore the complete ionic equation for the reaction 3 is as follows:

${\text{6N}}{{\text{a}}^+}\left({aq}\right)+2{\text{PO}}_4^{3-}\left({aq}\right)+3{\text{N}}{{\text{i}}^{2+}}\left({aq}\right)+6{\text{C}}{{\text{l}}^-}\left({aq}\right)\to{\text{N}}{{\text{i}}_3}{\left( {{\text{P}}{{\text{O}}_4}}\right)_2}\left(s\right)+{\text{6N}}{{\text{a}}^+}\left({aq}\right)+6{\text{C}}{{\text{l}}^-}\left({aq}\right)$
