Titration Flashcards
1
Q
Equivalence point
A
The point in a titration where the amount of titrant added is enough to completely neutralise the analyte solution
2
Q
End point
A
An approximation of the equivalence point
3
Q
Pipette
A
Wash with distilled water, then the solution going in it.
4
Q
Burette
A
The unkown solution is placed here(analyte) can be swapped. Washed with distilled water, then washed with the solution going in it.
5
Q
Conical flask
A
A known substance is placed here(titrant) can be swapped. Washed with distilled water
6
Q
Secondary Standard
A
A solution that has been prepared in the laboratory and has been titrated/standardised against a primary solution
7
Q
How to prepare a Primary standard
A
- Desiccated/dry standard is weighed accurately in a beaker(moles are known)
- It is mixed with distilled h20 until dissolved
- this is then dropped to a clean & dry volumetric flask and the beaker is rinsed with distilled water into the volumetric flask
- the volumetric flask is topped up dropwise and stoppered, labelled with the concentration, solution and date.
8
Q
Volumetric Flask
A
accurate measuring device to 4 sig. figs.
