Worked Solution & Example Answer:Which equation represents neutralisation? A 4H⁺ → 2H₂ B H₂O → 2H⁺ + O²⁻ C H⁺ + OH⁻ → H₂O D O₂ + H₂ → H₂O + O²⁻ Your answer - OCR Gateway - GCSE Chemistry - Question 2 - 2018 - Paper 1
Step 1
C H⁺ + OH⁻ → H₂O
Answer
This equation represents the neutralization process because it involves the reaction between hydrogen ions (H⁺) and hydroxide ions (OH⁻) to form water (H₂O). In neutralization reactions, an acid (providing H⁺) reacts with a base (providing OH⁻) to produce water and typically a salt.
