It will not dissolve in polar covalent water. Both compounds were nonpolar, indicating a similarity in polarity. Ethyl acetate and Naphthalene are both non-polar compound, thus Naphthalene dissolve in Ethyl acetate the best than other solvents. Favorite Answer. The compound sublimes (turns from a solid to a gas) slowly at room temperature, producing a vapor that is highly combustible. There is one precaution to consider in using the formic acid/hexane method as a sep- aration procedure for naphthalene metabolites. The solubility data of naphthalene in binary mixtures of carbon tetrachloride and cyclohexane, hexadecane, and hexane,5 for binary mixtures of toluene and carbon tetrachloride, cyclohex-ane, hexadecane, and hexane,4 and also for cyclohexane + hexane, hexadecane + cyclohexane, and hexadecane + hexane5 have been reported in the literature. So it will dissolve in the non-polar solvent hexane. Yes, the naphthalene will partially sublime, but your sublimation temp is way too low, I think it's 80 C. The solution is to use a cold finger to catch the naphthalene. Thus, it is insoluble in highly polar solvents like water. solubility data very closely and the be used to investigate factors affecting hydrocarbon solubility in physical solvents.

Naphtalene is soluble in hexane; the solubility in water is very low. Using a dynamic method, the solubilities of naphthalene in acetone, toluene, xylene, ethanol, heptane, and 1-butanol have been determined experimentally from (297.17 to 322.70, 291.35 to 334.65, 299.42 to 337.97, 304.26 to 339.76, 290.25 to 333.75, and 313.77 to 342.8) K, respectively. 1) Malic Acid in Water 2) Naphthalene in Water 3) Amphetamine in Ethyl Alcohol 4) Aspirin in Water 5) Succinic Acid in Hexane 6) Ibuprofen in Diethyl Ether 7) 1-Decanol in Water For some of them, I already have the answer and for others, I'm not sure. Naphthalene, a covalent molecular compound, is insoluble in water even with stirring but dissolves easily in hexane (second from left). Naphthalene is non-polar so it is soluble in hexane, but almost insoluble in water. Napthalene is soluble in hexane because "like dissolves like" What was the weather in Pretoria on 14 February 2013? Solubilities have been determined at 30, 35 and 40° C for biphenyl in carbon tetrachloride, cyelohexane, n-hexane, n-heptane and n-octane, and tor naphthalene in benzene, cyclohexane, toluene, ethylbenzene, carbon tetrachloride and n-hexane.Results of these measurements, combined with published data at 25 °C, are used to calculate the Wilson interaction parameters and to predict … why is Net cash provided from investing activities is preferred to net cash used? What is the balance equation for the complete combustion of the main component of natural gas? It is best known as the main ingredient of traditional mothballs How much money do you start with in monopoly revolution? Answer to: A solution contains naphthalene (C10H8) dissolved in hexane (C6H14) at a concentration of 11.39% naphthalene by mass. Since this product is a salt, it should be soluble in water. Therefore, their bonding was strong and effective. Naphthalene (NAF-thuh-leen) is a white crystalline volatile solid with a characteristic odor often associated with mothballs. 0 Comments Add a Comment Related Questions The C-H bonds that make up the molecule are considered to be non-polar becasue of the small difference in electronegativity between the two atoms. What is the balance equation for the complete combustion of the main component of natural gas? Naphthalene is non-polar so it is soluble in hexane, but almost insoluble in water.
