Question

When performing your experiment, you add your first drop of oleic acid/benzene solution, and a lens forms immediately. what is wrong with your setup, and how can it be corrected?

Answer 1

What's wrong with this setup is the substrate on which you have positioned the drop is "dirty and unclean" meaning it is not being dampened by the solution. This action can be corrected by comprehensively cleaning the substrate where the drop will be positioned.

Answer 2

Formation of lens occurs because the substrate is dirty and it can be corrected by proper cleaning the substrate on which drop is being added.

Further Explanation:

Proper thinking about any scientific problem, subject or content, observation, hypothesis, comparison, organization, prediction, experimentation, evaluation and application are included in wide term called scientific method.

Steps to proceed in scientific method:

• Understanding the experiment
• Pose a testable question
• Research the topic
• State a hypothesis
• Design the experiment
• Perform the experiment
• Data collection
• Draw conclusions

Experiment is a method or process designed for a particular purpose and is an important part of the scientific method. This includes both dependent and independent variables.

When performing the experiment, first drop of oleic acid or benzene solution is added and a lens is formed immediately. This occurs because the substrate on which the drop is being added is not clean and therefore it cannot become wet by addition of solution and forms a lens. This situation can be corrected by proper cleaning of the substrate on which drop of the solution is to be added.
