Titration (PAG C6) Flashcards

1️⃣ Familiarise yourself with the flashcards:

Look through all the flashcards to see what's on both sides.
Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

Look at the question or prompt on each card and try to remember the answer before flipping it over.
Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

What is a titration used for in chemistry?

A titration is used to find the unknown concentration of a solution by reacting it with a solution of known concentration.

A burette holds one solution and lets you add it slowly and measure the exact volume added in cm³.

A pipette is used to measure a fixed, accurate volume of solution, usually 25.0 cm³, into the conical flask.

A conical flask is used so you can swirl the mixture while adding solution without spilling it.

We add an indicator so we can see a colour change at the point where the acid and alkali have just reacted exactly.

The end point is the moment when the acid and alkali have reacted in the correct amounts and the indicator just changes colour.

We use a white tile so the colour change of the indicator is easier to see clearly.

Reading at eye level from the bottom of the meniscus avoids parallax error and gives a more accurate volume.

A rough titration shows you about what volume is needed, so you can add the solution more slowly near the end point in later, accurate titrations.

Concordant titres are repeat volume readings that are very close together, usually within 0.10 cm³ of each other.

You should wear safety goggles to protect your eyes, because acids and alkalis can irritate or damage them if they splash.
