What is the net ionic equation for the reaction between NH4+ and NaOH in aqueous solution?
A
NH4+ + Na+ → NH4Na
B
NH4+ + OH- → NH4OH
C
NH4+ + H2O → NH3 + H3O+
D
NH4+ + OH- → NH3 + H2O
Verified step by step guidance1
Identify the reactants and products involved in the reaction. Here, NH4+ and OH- are the reactants, and NH3 and H2O are the products.
Write the balanced molecular equation for the reaction: NH4+ + OH- → NH3 + H2O.
Determine the states of each species in the reaction. NH4+ and OH- are aqueous ions, NH3 is a gas, and H2O is a liquid.
Recognize that the net ionic equation includes only the species that undergo a change during the reaction. Spectator ions, which do not participate in the reaction, are omitted.
Since NH4+ and OH- directly form NH3 and H2O without any spectator ions, the net ionic equation is simply NH4+ + OH- → NH3 + H2O.
