volumetric analysis Flashcards
1
Q
what is volumetric?
A
using a known solution to determine an unknown solution
2
Q
standards
A
- known chemical formula
- large molar mass to minimise errors
- do not react with surrounding environment
- cheap and readily available
- pure substance
3
Q
neutralisation reaction produces
A
salt and water
4
Q
washing equiptment
A
flasks washed with distilled water
burette and pipette with solution they will deliver
integrity of concentration
5
Q
indicator use
A
acids and bases are colourless
6
Q
equivalence point
A
the point at which the amount of each reactant is equal. the amounts in mol as equal to the stoich
7
Q
end point
A
the reaction is over
8
Q
how do you choose an indicator?
A
on acids and bases

Q
weak
A
does not donate or accept readily
