Solubility of Liquids Experiment

Aravind conducts an activity from the NCIT textbook to test the solubility of various liquids in water. The experiment involves adding vinegar, lemon juice, mustard oil, coconut oil, and kerosene to separate glasses of water, stirring them, and observing the results. Vinegar and lemon juice are found to be soluble, while mustard oil, coconut oil, and kerosene are insoluble, forming separate layers. The activity concludes with a summary of the findings.

What is the first step in preparing for the solubility experiment?

• Fill glasses with water.
