At temperatures above 5°C, the benzenediazonium ion, C₆H₅N₂⁺, reacts with water as shown. C₆H₅N₂⁺(aq) + H₂O(l) → C₆H₅OH(aq) + N₂(g) + H⁺(aq) A student investigates this reaction by measuring the volume of nitrogen gas produced at regular time intervals. The diagram shows the experimental set-up used to investigate this reaction. [Figure showing a conical flask with C₆H₅N₂⁺(aq) connected to a gas syringe]
