Question:
Write the complete molecular reaction, the complete (full) ionic equation, and lastly, the net ionic equation for the following:
{eq}\displaystyle \rm Zn(NO_3)_2 + NaOH \to {/eq}
Molecular Reaction:
Molecular reactions describe the balanced chemical reaction between the reactants to form the products.
Molecular reactions help to write the two other types of reaction equations as follows:
- Ionic equation
- Net ionic reactions
Answer and Explanation: 1
The reaction between the zinc nitrate {eq}\rm Zn{\left( {N{O_3}} \right)_2}{/eq} and sodium hydroxide (NaOH) forms the product zinc hydroxide {eq}\rm Zn{\left( {OH} \right)_2} {/eq} and sodium nitrate {eq}\rm \left( {NaN{O_3}} \right) {/eq} the complete molecular reaction is represented as follows:
{eq}\rm Zn{\left( {N{O_3}} \right)_2}\left( {aq} \right) + 2NaOH\left( {aq} \right) \to Zn{\left( {OH} \right)_2}\left( s \right) + 2NaN{O_3}\left( {aq} \right){/eq}
A complete ionic equation is written by splitting the strong electrolyte into their ions as follows:
{eq}\rm Z{n^{2 + }}\left( {aq} \right) + 2NO_3^ - \left( {aq} \right) + 2N{a^ + }\left( {aq} \right) + 2O{H^ - }\left( {aq} \right) \to Zn{\left( {OH} \right)_2}\left( s \right) + 2N{a^ + }\left( {aq} \right) + 2NO_3^ - \left( {aq} \right){/eq}
The net ionic equation is written by canceling the {eq}\rm NO_3^ - and\;N{a^ + }{/eq} ( common/spectator ions) in the reactant, and the product side is represented as follows:
{eq}\rm Z{n^{2 + }}\left( {aq} \right) + 2O{H^ - }\left( {aq} \right) \to Zn{\left( {OH} \right)_2}\left( s \right){/eq}
Thus, the molecular, ionic, and net ionic equations for the given reactant are represented above.
