Question
Lab: Solubility
Answers
Answered by
GPT 3.5
Aim: To investigate the solubility of different substances in water and other solvents.
Materials:
- Water
- Sugar
- Salt
- Sand
- Alcohol
- Vinegar
- Hot plate or stove
- Beakers or cups
- Stirring rods
- Filter paper
- Funnel
Procedure:
1. Prepare a set of labeled beakers or cups for each substance to be tested.
2. Add a small amount of each substance (sugar, salt, sand) to separate beakers or cups.
3. Add a known amount of water to each beaker or cup and stir to dissolve the substance.
4. Observe and record whether each substance dissolves in water.
5. Repeat steps 2-4 with alcohol and vinegar as the solvent instead of water.
6. If any substance does not dissolve in the solvent, try heating the mixture on a hot plate or stove to see if it will dissolve.
7. Use filter paper and a funnel to separate any undissolved material from the solvent.
8. Compare the solubility of each substance in water, alcohol, and vinegar.
Results:
- Sugar should dissolve in water, alcohol, and vinegar.
- Salt should dissolve in water and vinegar, but not in alcohol.
- Sand should not dissolve in any of the solvents.
- Alcohol should dissolve in water and vinegar.
- Vinegar should dissolve in water and alcohol.
Conclusion:
The solubility of a substance depends on the solvent used. Some substances are soluble in water but not in alcohol or vinegar, while others may be soluble in multiple solvents. Understanding the solubility of different substances is important in various applications, such as chemistry, medicine, and food science.
