Are Crystals of Salt Really Dry?
Salt crystals are typically considered dry because they do not contain any water molecules within their structure. However, to confirm this, an experiment can be conducted to determine if salt crystals are truly dry.

Experiment to Test if Salt Crystals are Dry:
1. Materials Needed:
- Salt crystals
- Weighing scale
- Bunsen burner
- Test tube
- Rubber stopper with a hole
- Glass tubing
- Calcium chloride pellets
2. Procedure:
a. Weigh an empty test tube and record the weight.
b. Add a small amount of salt crystals into the test tube and weigh it again.
c. Attach the rubber stopper with glass tubing to the test tube.
d. Place the test tube over a Bunsen burner and heat the salt crystals gently.
e. As the salt crystals heat up, any water present will evaporate and be collected by the calcium chloride pellets in the glass tubing.
f. Continue heating until no more water is collected in the glass tubing.
3. Observations:
- If no water is collected in the glass tubing, it confirms that the salt crystals are indeed dry.
- Any water collected in the glass tubing would indicate the presence of water within the salt crystals.
4. Conclusion:
By conducting this experiment, it can be determined whether salt crystals are truly dry or if they contain any water molecules. This experiment provides a clear answer to the question of whether the crystals of salt are dry.
