1
Q
what is back titration used to work out?
A
the quantity of substance in a solid with low solubility
2
Q
when else might a back titration be used?>
A
if the direct titration is too slow of there is no suitable indicator for it
3
Q
what is the first stage of a back titration?
A
the substance being analysed (chemical A) is reacted with an excess volume of a reactant of known concentration (chemical B)
4
Q
what is the second stage of a back titration?
A
the resulting mixture is titrated with a chemical that reactions with chemical B (chemical C)
