On the other hand, oil being non-polar does not dissolve in polar solvent like water. 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. The bonds are arranged symmetrically so there is no overall dipole in the molecule. The molecule is CH3 - COOH. The -OH groups are polar. Lv 6. Answer Save. (Hint: Like substances dissolve like substances, and polar solvents dissolve ionic compounds.) In table two, indicate whether the solutes (vinegar and iodine solution) are soluble in the solvent (water). Dry-cleaning solvents are polar. Oil is nonpolar. It is 4-5% acetic acid dissolved in water and that is polar. vinegar is polar. Examples of non-polar solvents: carbon tetrachloride (CCl4), benzene (C6H6), ... Vinegar, for example, is a solution of acetic acid in water. 3. Gasoline is nonpolar. Fat is nonpolar. Rule of thumb: Anything that can dissolve in water is polar. Vinegar is basically a water solution of acetic acid. 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. Vinegar is polar. The polar particles of salad oil are attracted to the nonpolar particles of the vinegar. Favorite Answer. not vinegar as a substance, but the molecule. Mix the contents with a stirring stick. Then conclude whether the compound is polar, nonpolar, or ionic. 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. Then conclude whether the compound is polar, nonpolar, or ionic. If the ink is attracted to oily fingers, then it is nonpolar. Oils repel polar molecules such as those found in vinegar. Hydrocarbons are nonpolar. Ethanol is polar. If you believe it will, then it will be non-polar. Therefore, vinegar being polar will dissolve in polar solvent like water. Nail polish is polar. Non-polar solvents are liphophilic as they dissolve non-polar substances such as oils, fats, greases. Mix the contents with a stirring stick. Polar chemicals generally are soluble in water. Vinegar or acetic acid is a polar molecule whereas oil is a chain of hydrocarbons which are insoluble in water. Relevance. Oil is nonpolar. 3 Answers. One way to think about it is to observe (or postulate) that it will mix with oil. Oil based paints are nonpolar. In table two, indicate whether the solutes (vinegar and iodine solution) are soluble in the solvent (water). Each bond has polarity (though not very strong). 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. However, polar and non polar chemicals do not mix. 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. A polar molecule has a positive charge on one end and a negative charge on the opposite end. Also, it is known that water is a polar solvent and like dissolves like. This is where the saying “like oil and water” comes from. Is a vinegar molecule polar or nonpolar? (Hint: Like substances dissolve like substances, and polar solvents dissolve ionic compounds.) "Like" dissolve "like". 1st Liberal. 3. and why? Vitamin A is polar. Vitamin C is polar. Many nonpolar organic solvents, such as turpentine, are able to dissolve non-polar substances. By the way, if it dissolves in water, that is a good bet that it is polar. Other examples of polar chemicals include alcohol and vinegar. In the methane molecule (CH 4) the four C−H bonds are arranged tetrahedrally around the carbon atom. Anything that can't, is non polar.
