Ethanol is less polar as it has a polar -OH group and a non-polar CH3. Maybe a reason could be that because water is more polar it is held together more strongly so does not therfore react with the impurities are readily as ethanol.Help would be greatly appreciated. *Ignore me, I am...
Polar Covalent Bonds: A covalent bond where there is discernible electronegativity between two atoms. Dipole: A condition where the positive and negative charges between atoms are separate from each other. London Force: Instantaneous dipole creation that affects the electronegativity between atoms. It ...
Re:why is aspirin more soluble in ethanol than in water? «Reply #1 on:January 04, 2006, 05:23:40 PM » The aspirin molecule is made up of a benzene ring, a carboxyl group, and an ester. It has both polar and non-polar components. Thus, the affinity of water (very polar) fo...
Will the given solid compound dissolve in water? Why or why not? PbO2 Explain why benzophenone is more soluble in acetate than in water. Explain why calcium sulfate is less soluble in sodium sulfate solution than in pure water. Explain why non-ionic compounds, such as ethanol or sugar, are...
These are much weaker than the chemical bonds but are essential in determining the overall property of the compound. For instance, the fact that water has a higher boiling point than methanol even though methanol has a higher molar mass is explained by the IMFA present....
Why do alkanes not dissolve in water but dissolve in benzene? Becausealkanes are non-polarand water is a polar solvent. Why pyridine is water soluble but not pyrrole? Explanation: Pyridine, C6H5N , features a nitrogen centre that is more electronegative than the carbocyclic carbons of the ben...
An additional ethanol wash of nucleic acids-bound column was performed to further wash out impurities. The resulting nucleic acids were eluted with 5 ml RNase-free deionized water and further concentrated using ethanol precipitation overnight and re-eluted in 100 ml of TE buffer. The ...
Cells were then washed three times in PBS, postfixed with 1% OsO4 for 1.5 h and washed three times with distilled water and stored overnight at 4C. Samples were dehydrated 15 min in a graded series of ethanol (25%, 50%, 75%, 95%...
Why does sugar dissolve but not dissociate in water even though it is a polar molecule? Why is tap water more conductive than distilled water? Why don't lipids and water mix? Explain why some substances are soluble in water and some are not? Respond to the statement: "like dissolves like...
Water's large dipole moment makes it a polar solvent. In polar solvents, the bonded atoms have different electronegativity, which is the tendency of atoms to attract electrons. Polarity can be used to describe the on or off states of bits in computing. Quantum bits subvert this paradigm. Lear...
