Neutralisation Flashcards
When an alkali is added to an acid….
The solution becomes less acidic
When an acid is added to an alkali….
The pH of the alkali decreases
One way that acids and alkalis can be mixed carefully is….
By titration
Titration = a technique where a solution of known concentration is used to determine the concentration of an unknown solution.
What is the word equation for neutralisation?
Acid + alkali ——> salt + water
What is neutralisation?
The chemical reaction that occurs when an acid and an alkali are mixed.
What part of the alkali reacts with what part of the acid?
The hydrogen of the acid reacts with the hydroxide of the alkali
What does a Burette allow us to do?
A burette allows an acid to be added to an alkali gradually. If the acid is added slowly enough, the neutral point (pH 7) can be seen. This point is indicated by the solution turning green.
What is meant by the end point of neutralisation?
When this is said, it can mean the exact point that the solution became neutral.
