Titrations (chemistry Only) (GCSE Chemistry)

In a titration calculation you find the moles of titrant used and want moles of analyte. Which information must you use next?

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:

A student obtains titration readings of 23.50, 23.55 and 23.60 cm3 for concordant titres. Which value should be used as the titre in calculations?

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

What is the main purpose of rinsing a burette with the solution that will be placed in it before filling?

To reduce random error in titration timings and mixing, the best practice is to:

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

Which statement about the equivalence point in a titration is correct?

If a burette has a zero error where the initial level is 0.10 cm3 below the true zero, how should the recorded titration volume be corrected?

What is the best description of a primary standard for preparing a standard solution for titration?

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?
