 The  net ionic  equation for  the neutralization  reaction involving  equal molar amount amount of  HNo3  and KoH  is 

H^+   +  OH^-  =  H2O (l)

    explanation
write  the   chemical equation
HNO3 (aq) + KOH(aq) =  KNO3(aq) +H2O  (l)

ionic   eequation

H^+(aq)  +  NO3^- (aq) +  K^+9aq)   OH^-(aq) = K^+ (aq) + NO3^-(aq)  + H2O(l)


cancel the  spectator  ions( ions which  does  not  take  place in  equation ) for this case    is  NO3^-  and  No3^-

thus the  net ionic  is


H^+(aq)  + OH^- (aq)  =  H2O(l)

Answer: H⁺(aq) + OH⁻(aq) --> H₂O(l)


Explanation:


1) Write the molecular chemical equation:


HNO₃(aq) + KOH(aq) ---> H₂O(l) + KNO₃(aq)


2) Identify the kind of reaction:


It is a acid base neutralization, which is a double replacement equation.


3) Set the ionization (dissociation) of the acid and the base compounds:


i) HNO₃(aq) ---> H⁺ (aq) + NO₃⁻ (aq)

ii) KOH (aq) --> K⁺ (aq) + OH⁻ (aq)


4) Identify whether the products are soluble ionic compounds and they dissociate in water or remain solids (phases).


i) KNO₃ is soluble, so it will dissociate: KNO₃(aq) --> K⁺(aq) + NO₃⁻(aq)


ii) H₂O slightly dissociates, so it will remain liquid: H2O (l)


5) Write the total ionic equation:


H⁺ (aq) + NO₃⁻(aq) + K⁺(aq) + OH⁻ (aq) --> K⁺ (aq) + NO₃⁻(aq) + H₂O(l)


6) Eliminate the spectator ions (those that are repeated in reactant and product sides, K⁺(aq) y NO₃⁻(aq):


H⁺(aq) + OH⁻(aq) --> H₂O(l)


That is the net ionic equation.
