Question 101

A student carries out a titration to find the concentration of a nitric acid solution using a standard solution of sodium carbonate.

An outline of the method is shown below:

  1. A volumetric pipette is used to measure 25.00 cm3 of sodium carbonate solution into a conical flask.
  2. A few drops of methyl orange indicator are added to the flask.
  3. A burette is filled with the nitric acid.
  4. The nitric acid is added slowly to the sodium carbonate solution until the end-point is reached.

Describe how the pipette should be used to measure exactly 25.00 cm3 of the sodium carbonate solution into the conical flask.
