Which of the following phenomena usually occurs when a strong acid is diluted?
- A.Ionization and dilution only
- B.Neutralization and dilution only
- C.Formation of hydronium ions, followed by absorption of heat
- D.Formation of hydronium ions, accompanied by release of heatCorrect answer
Solution
When a strong acid is diluted, water molecules interact with the acid to form hydronium ions (). This process is highly exothermic, meaning it is accompanied by the release of heat.
