Titrations (chemistry Only) (GCSE Chemistry)

Why is a conical flask used during titration rather than a beaker?

Which error will shift all titre results by the same constant amount (systematic error) and so give an incorrect concentration?

When titrating a weak acid with a strong base, the suitable indicator is one that changes colour at pH > 7. Which indicator is appropriate?

A student prepares 250.0 cm3 of 0.100 mol/dm3 sodium hydroxide from a 2.00 mol/dm3 stock solution. What volume of stock solution is needed?

Which of the following would give the most precise titration results?

Which procedure increases accuracy when preparing a standard solution by weighing a solid?

Which piece of apparatus is used to deliver a very accurate fixed volume of solution to the titration flask before titration?

During an acid–base titration the indicator changes colour at the end-point. Which statement best describes the end-point?

A student titrates an acid and then repeats the titration and obtains very different titres because the indicator was added too early in the first run. This is an example of:

When titrating a weak acid with a strong base, the pH at the equivalence point is typically:

What does the term “concordant titres” mean?
