Key Points
Salt dissolves well in water, less in vinegar, not in oil.
Key Points / Good Practices
- Use the same amount of salt and solvent for a fair test.
- Stir each for the same time and observe.
- Salt dissolves easily in water.
- It dissolves in vinegar too, as vinegar is mostly water.
- Salt does not dissolve in oil.
- Record your observations in a neat table.
A fair test shows salt dissolves in water and vinegar but not in oil.
