When sulfuric acid (H2SO4) reacts with potassium hydroxide (KOH) in an aqueous solution, the following net ionic equation can be written:
H+ + OH- → H2O
In this reaction, sulfuric acid (H2SO4) dissociates into hydrogen ions (H+) and sulfate ions (SO4^2-). Potassium hydroxide (KOH) dissociates into potassium ions (K+) and hydroxide ions (OH-). The hydrogen ions (H+) from sulfuric acid combine with the hydroxide ions (OH-) from potassium hydroxide to form water (H2O).
It's important to note that the potassium ions (K+) and sulfate ions (SO4^2-) do not directly participate in the reaction and remain unchanged as spectator ions. Therefore, they are not included in the net ionic equation.
