Question

250. Definition (produces hydronium ions on dissolution in water)

(c) Nitric acid HNO₃ + H₂O 🡪

Answer 1

• When an acid is added to water, it will dissociate into its ions and produce H⁺ ions.
• The H⁺ ions combine with water and form hydronium ions (H₃O⁺).
• Nitric acid is a relatively strong acid, meaning it tends to ionize almost completely in an aqueous solution.
• Nitric acid on hydrolysis produces H₃O⁺ ions and nitrate (NO₃^-) ions.
• The chemical equation for the given reaction is as follows:

HNO₃ + H₂O 🡪 H₃O⁺ + NO₃^-

Nitric acid water hydronium ion nitrate
