The ink does not dissolve well in water but it does easily in the alcohol, giving the latter much more color. Soap will help the two liquids dissolve in each other. This allows the saline solution to conduct electricity, which is the reason why they are called electrolytes. Sugar, on the other hand, does not break up into charged particles. The term hydrophobic literally means... See full answer below. Oil (as in hydrocarbon-based oils) and water have very different dipole moments, so oil and water do not readily dissolve in each other. I think they dissolve differently because some of the salt did not dissolve and sugar is much more soluble in water than is salt . Different substances have different solubilities. 3 comments. Temperature affects dissolving but doesn't have the same effect on all substances. 13 points Why does salt and sugar dissolve in water but not oil? Tell me, does table salt dissolve in glycerin? It explains why oil (nonpolar) separates from water (polar), yet salt (polar) dissolves in water. The Na+ and Cl- would prefer to stay with each other where they have nice ionic interactions..the result is that the salt does not dissolve. Previous question Next question Get more help from Chegg. The solubility of sugar increases with temperature at a greater rate compared to salt. Since water is a very polar molecule, and oils tend to be very non-polar, it is easier to dissolve a non-polar compound in oil! ... Salt Conducts Electricity, Sugar Does Not.
