Which net ionic equation represents the neutralization of ANY strong acid by ANY strong base in water?
A.H⁺ + OH⁻ → H₂O
B.HCl + NaOH → NaCl + H₂O
C.HA + B → HB⁺ + A⁻
D.2 H₂O → H₃O⁺ + OH⁻
Explanation
Core Concept
Once dissolved, strong acids exist as H₃O⁺ and strong bases as OH⁻, so molecular formulas drop out of the net equation. Every strong-strong neutralization reduces to one proton joining one hydroxide to form water. Spectator ions change with the reagents chosen, but the net ionic reaction never does.
Correct Answer
AH⁺ + OH⁻ → H₂O
