In this experiment, I will determine how much drink powder it will take to make a saturated solution, that is, a solution in which no more solute (drink powder) can dissolve in a solvent (water).
Hypothesis:
1. If I add ____ spoonfuls of drink powder to room-temp water, then I think it will dissolve to form an unsaturated solution, that is, a solution in which more solute can be dissolved.
2. If I add ____ spoonfuls of drink powder to room-temp water, then I think will dissolve to form a saturated solution, that is, a solution in which no more solute can dissolve.
Procedure:
1. Measure 100ml of water. Add 1 spoonful (5ml or 4gr) of drink powder. Stir.
2. Continue adding spoonfuls of drink powder, stirring after each one.
3. Stop adding drink powder when no more will dissolve.
Observations:
I noticed that ________ spoonfuls of drink powder dissolved in 100ml of water. (1 spoonful measures 5ml or 4gr x ___#of spoonfuls = ___ml or ___gr of solute)
Analysis:
Concentration = mass of solute / 100ml of solution
___gr / 100ml of solution = ____gr / 200ml
Conclusion:
What did you learn about the solubility of a solute?
How accurate was your hypothesis?
