• neutralisation

• alkalisation

Hydrochloric acid reacts with Sodium hydroxide and forms water and

What method is used to study the neutralisation reaction between an acid and an alkali?

• Evaporation
• Titration
• Sublimation
• Electrolisis

In a neutralisation reaction, what is the function of the indicator?

• To indicate that the mixture is neutral
• To indicate that hot water should be added
