How to Prepare 0.1M of Sucrose
Sucrose solution can be made from common table sugar. (spoonful of sugar image by Brett Mulcahy from Fotolia.com)

To prepare a 0.1M sucrose, simply mix 0.1 moles of sucrose, which is equivalent to 34.2 grams, with enough deionised water to make 1 litre of solution. With a bit of preparation, you can prepare the solution using proper laboratory methods.

Instructions

  1. 1

    Place a magnetic stir bar into a glass beaker on a magnetic stirrer.

  2. 2

    Weigh out 32.4g of sucrose into the beaker. This is equivalent to 0.1 moles.

  3. 3

    Pour 500ml of deionised water into the beaker.

  4. 4

    Turn on the magnetic stirrer and allow the solution to mix until all of the sucrose is dissolved.

  5. 5

    Pour the solution into a 1-liter graduated cylinder, retaining the stir bar in the beaker.

  6. 6

    Fill the graduated cylinder to the 1-liter mark with the remaining deionised water.

  7. 7

    Pour the solution back into the beaker containing the stir bar and place on the magnetic stirrer for one minute to thoroughly mix.

  8. 8

    Pour the sucrose solution into a 1-liter bottle for storage, retaining the magnetic stir bar in the beaker.

Tips and warnings

  • You can use plain table sugar to make this solution.
  • Be sure to use a graduated cylinder to measure 1 litre of solution after the sucrose has been added rather than adding 1 litre of water to the measured sucrose. Adding 1 litre of water will result in a solution that is slightly less than 0.1M.
