H2SO4­ + Zn(NO3)2 net ionic equation

H­2SO4 + Zn(NO3)2 net ionic equation is as follows;

No ReZn2+ (aq.) + 2NO3– (aq.) + 2H+ (aq.) + SO42- (aq.) = Zn2+ (aq.) + SO42- (aq.) + 2H+ (aq.) + 2NO3– (aq.)action

To obtain the net ionic equation, following steps should be obeyed:

  • Write down the general balanced molecular equation.
  • Zn(NO3)2 + H2SO4­ = ZnSO4 + 2HNO3
  • Specify each compound with its chemical state like solid, liquid or gas.
  • Zn(NO3)2 (aq.) + H2SO4­ (aq.) = ZnSO4 (aq.) + 2HNO3(aq.)
  • Break the electrolytic compounds into their ionic forms.
  • Eliminate the spectator ions present on the both sides of chemical equation. In our case, all the ions are spectator ions; therefore, this is a case of No Reaction.

H2SO4­ + Zn(NO3)2 conjugate pairs
