Benzene C6H6, is a liquid at room temperature. Which compound in each pair would be more soluble in water? "BTW, odor is a highly variable thing (check the odor threshold of methyl mercaptan and compare it to say, heptane), so just saying something stinks doesn't say anything about its evaporation rate. I think sodium fluoride will be more soluble because there will be hydrogen bonding between the fluoride and the hydrogen. 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. Their properties of solubility with water or ethanol was either slightly soluble or insoluble, making extraction by solubility a definite no with using this experiment to separate the mixture. We saw that ethanol was very water-soluble (if it were not, drinking beer or vodka would be rather inconvenient!) Ethyl Alcohol is easily soluble. b.) Are amphetamine and ethyl. The presence of the hydroxyl group, #"-OH"#, is what makes ethanol a polar molecule.However, the nonpolar ethyl group, #CH_3CH_2"-"#, is what allows naphthalene to be partially soluble in ethanol.. Naphthalene is said to be somewhat soluble in ethyl alcohol (ethanol). 1) Malic Acid in Water 2) Naphthalene in Water … This means that it is not soluble in water, but is soluble in ethanol. Would boric acid, B(OH)3, be more soluble in ethanol (C2H5OH) or in benzene (C6H6)? As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings. Ethyl acetate and Naphthalene are both non-polar compound, thus Naphthalene dissolve in Ethyl acetate the best than other solvents. a.) Naphthalene, which is nonpolar, and phenol (C 6 H 5 OH), which is polar, are very soluble in chloroform. … Ethanol and petroleum are easily flammable and can be set on fire. Solubility is the property of a solid, liquid or gaseous chemical substance called solute to dissolve in a solid, liquid or gaseous solvent.The solubility of a substance fundamentally depends on the physical and chemical properties of the solute and solvent as well as on temperature, pressure and presence of other chemicals (including changes to the pH) of the solution. It was then placed into a mortar and ground up into a fine powder. It is insoluble in water, somewhat soluble in ethanol, soluble in benzene, and very soluble in ether, chloroform, or carbon disulfide. naphthalene năf´thəlēn˝ , colorless, crystalline, solid aromatic hydrocarbon with a pungent odor.
