To prepare a 0.1M sucrose, simply mix 0.1 moles of sucrose, which is equivalent to 34.2 grams, with enough deionized water to make 1 liter of solution. With a bit of preparation, you can prepare the solution using proper laboratory methods.
Making the Sucrose Solution
- 34.2 grams of sucrose (table sugar)
- 1 liter of deionized water
- 1-liter graduated cylinder
- 1-liter beaker
- 1-liter bottle
- Magnetic stirrer
- Magnetic stir bar
You can use plain table sugar to make this solution.
Be sure to use a graduated cylinder to measure 1 liter of solution after the sucrose has been added rather than adding 1 liter of water to the measured sucrose. Adding 1 liter of water will result in a solution that is slightly less than 0.1M.
Place a magnetic stir bar into a glass beaker on a magnetic stirrer.
Weigh out 32.4 g of sucrose into the beaker. This is equivalent to 0.1 moles.
Pour 500 mL of deionized water into the beaker.
Turn on the magnetic stirrer and allow the solution to mix until all of the sucrose is dissolved.
Pour the solution into a 1-liter graduated cylinder, retaining the stir bar in the beaker.
Fill the graduated cylinder to the 1-liter mark with the remaining deionized water.
Pour the solution back into the beaker containing the stir bar and place on the magnetic stirrer for one minute to thoroughly mix.
Pour the sucrose solution into a 1-liter bottle for storage, retaining the magnetic stir bar in the beaker.
