C5.1.5 - Titrations Flashcards
1
Q
What is titration?
A
A method in which a neutralisation is used to determine the concentration of an acid or alkali
2
Q
What is a burette?
A
A graduated tube with a tap used in titrations
3
Q
What is the end-point?
A
The point at which the 2 reactants in a titration have exactly reacted together
4
Q
What is a titre?
A
A measured volume of solution added from a bursts during a titration to reach the end-point
5
Q
What are concordant titres?
A
Results from a titration that are within 0.10cm3 of each other
6
Q
How do you prepare to carry out a titration?
A
- You use a volumetric pipette to measure 25cm3 of alkali solution for the conical flask. You need a pipette filler to use a volumetric pipette safely
- The burette must be clamped vertically so you obtain accurate readings
- When you have filled the burette with acid, and added a few drops of indicator to the alkali in the conical flask, you are ready

Q
What is a volumetric pipette?
A
A piece of glassware used to measure an accurate volume of solution for a titration
8
Q
What is a pipette filler?
A
Device to draw liquid into a pipette safely
