Molecular Structure Lab Report: Determining Polarity
Instructions: For this investigative phenomenon, you will investigate why certain substances, such as oil and vinegar, don't mix. To do so, you will combine various compounds, compare their solubility, and determine their polarity. Fill in each section of this lab report and submit it to your instructor for grading.
Title: Determining Polarity, Gabriella Anzelc, Mrs. Stockman

Objective(s): Comparing the solubility of different compounds and determining their polarity of them based on the solubility.

Hypothesis:
Create a hypothesis that predicts the polarity of iodine solution, vinegar, vegetable oil, salt, water, and rubbing alcohol.
If the compounds (iodine solution, vinegar, vegetable oil, salt, water, and rubbing alcohol) dissolve in water, the compounds are

It will be helpful to refer to your chemistry journal notes. Answer questions in complete sentences.
Were any of your substances difficult to identify as polar, nonpolar, or ionic? Explain.
One of the substances that was difficult to identify as polar, nonpolar, or ionic was the iodine solution. Iodine is a solid at room temperature and it is not clear-cut if it is polar or nonpolar. Iodine is a nonmetal and it forms a polar covalent bond with chlorine, but it also forms a covalent bond with other non-metals like sulfur which is nonpolar.

How do models help scientists predict the polarity of molecules?
Models aid in predicting the polarity of molecules by providing a visual representation of the arrangement of atoms and electrons within a molecule. They allow scientists to infer the polarity and predict solubility by understanding the distribution of electrons and shape of a molecule. They also allow scientists to make educated guesses about new compounds' polarity by comparing them to known polar or nonpolar
