8 years ago. It is 4-5% acetic acid dissolved in water and that is polar. However, polar and non polar chemicals do not mix. In table two, indicate whether the solutes (vinegar and iodine solution) are soluble in the solvent (water). The -OH groups are polar. Oils repel polar molecules such as those found in vinegar. Examples of non-polar solvents: carbon tetrachloride (CCl4), benzene (C6H6), ... Vinegar, for example, is a solution of acetic acid in water. Oil is nonpolar. If you believe it will, then it will be non-polar. The bonds are arranged symmetrically so there is no overall dipole in the molecule. Oil doesn't stay dissolved because the water molecules are polar and are strongly attracted to each other to the point that the oil molecules are excluded. Non-polar solvents are liphophilic as they dissolve non-polar substances such as oils, fats, greases. Vinegar or acetic acid is a polar molecule whereas oil is a chain of hydrocarbons which are insoluble in water. One way to think about it is to observe (or postulate) that it will mix with oil. 3 Answers. Oil based paints are nonpolar. Dry-cleaning solvents are polar. Rule of thumb: Anything that can dissolve in water is polar. Vinegar is basically a water solution of acetic acid. (Hint: Like substances dissolve like substances, and polar solvents dissolve ionic compounds.) vinegar is polar. Also, it is known that water is a polar solvent and like dissolves like. Many nonpolar organic solvents, such as turpentine, are able to dissolve non-polar substances. This is where the saying “like oil and water” comes from. Please understand that polar or nonpolar is a continuous range, not an either or. Therefore, vinegar being polar will dissolve in polar solvent like water. Relevance. Then conclude whether the compound is polar, nonpolar, or ionic. Vinegar is polar. not vinegar as a substance, but the molecule. Nail polish is polar. In table two, indicate whether the solutes (vinegar and iodine solution) are soluble in the solvent (water). On the other hand, oil being non-polar does not dissolve in polar solvent like water. Answer Save. Vitamin A is polar. Mix the contents with a stirring stick. Other examples of polar chemicals include alcohol and vinegar. Favorite Answer. 3. Lv 6. 3. Ethanol is polar. It is polar, any time you have something with a lone pair, you can bet it will be polar unless you have some crazy dipole cancellations. Iodine solution Vinegar No Ionic Nonpolar Vegetable oil Vinegar Yes Nonpolar Nonpolar Conclusion Write a conclusion statement that addresses the following questions: Due to Covid-19 pandemic, I used the internet to research the answers to this lab, so that is how I determined the polarity of these substances. (Hint: Like substances dissolve like substances, and polar solvents dissolve ionic compounds.) "Like" dissolve "like". The polar particles of salad oil are attracted to the nonpolar particles of the vinegar. Gasoline is nonpolar. Hydrocarbons are nonpolar. If the ink is attracted to oily fingers, then it is nonpolar. A polar molecule has a positive charge on one end and a negative charge on the opposite end. Is a vinegar molecule polar or nonpolar? Fat is nonpolar. 1st Liberal. Where the carbons are bonded, and the center carbon has a double bond to on oxygen, and a single bond to another but the one with the single bond has an H. Then conclude whether the compound is polar, nonpolar, or ionic. Mix the contents with a stirring stick. Anything that can't, is non polar. In the methane molecule (CH 4) the four C−H bonds are arranged tetrahedrally around the carbon atom. Polar chemicals generally are soluble in water. and why? The molecule is CH3 - COOH. Because oils also repel water, they are called hydrophobic, which means “water-fearing.” The carbon (black) and hydrogen (white) in this non-polar fatty acid molecule share electrons evenly and are neither negatively or positively charged. Vitamin C is polar. By the way, if it dissolves in water, that is a good bet that it is polar. Each bond has polarity (though not very strong). Oil is nonpolar.
