Which method is used to prepare soluble salts by neutralisation?

• A. Characteristic reaction method
• B. Titration method (neutralisation)
• C. Direct crystallisation
• D. Electrolysis

Answer: (B)

Titration is used because it lets you control the neutralisation very precisely. By measuring a known volume of acid (or alkali) and then adding the opposite reactant until the solution just reaches neutral, you know exactly how much has reacted. This exact balance gives you a solution containing the salt in a known amount or concentration. From there, you can evaporate water to crystallise the salt, giving a pure, soluble salt product. Other methods don’t provide that precise measurement of how much acid and base reacted, so they’re not as reliable for making a soluble salt by neutralisation.
