Standard solution
A solution with a known concentration
Making a standard solution from a more concentrated solution
Volume to use = (Final conc / initial conc) x volume required.
What can be learnt from titrations
How much acid is needed to neutralise a quantity of alkali and vice versa
Why is a rough titration carried out first
To get an idea of where the end point is
Calculating mean titre
Exclude rough titration, and use concordant results
Concordant results
Titres that are within 0.10 cm3 of each other
What properties of methyl orange and phenolphthalein good indicators for titrations
Change colour quickly over small changes in pH
What colour is methyl orange in acid and alkali
In acid it is red
In alkali it is yellow
What colour is phenolphthalein in acid and alkali
In acid it is colourless
In alkali it is red
