A saturated solution contains the maximum amount of solute that can be dissolved in a given amount of solvent at a given temperature.
Preparing a saturated salt solution:
Sodium chloride has a solubility of 35.7 grams in 100 cm3 of COLD water. That would be 357 grams of NaCl in one liter of H2O.
- Weigh out 357 grams of NaCl.
- Add the salt to a 1 liter volumetric flask.
- Add H2O at room temperature to the graduation line and stir until dissolved.
- You now have "saturated" salt water.
- What is the volume of the solution?
- How many moles of NaCl are in the sample?
- How many particles of sodium chloride are in this sample?
- How many sodium ions, Na+, are in this sample?
