Question

What is the balanced net ionic equation for the reaction below in basic solution? Enter the coefficient for each substance. Do not leave any answer box blank. Enter 1 if appropriate, or 0 (zero) if the substance does not appear on that side of the equation. NO21- + Al + OH1- + H2O right arrow NH3 + AlO21- + OH1- + H2O

Answer 1

Balancing equation in the presence of basic medium:
* separate the reaction into Oxidation Half Reaction (OHR) and Reduction Half Reaction (RHR)
* Balance other than oxygen and hydrogen atoms.
* To Balance the oxygen atoms add H2O.
* To Balance the hydrogen atoms add H+

* To balance H+ ions add OH- ions

* Combine H+ and OH- as H2O
* To Balance the charge add electrons
* Multiply the both equations with suitable coefficient to get the same number of electrons in both reactions
* Combine both oxidation and reduction half reaction.
