Electrolytes Lab Report

In procedure A, one must know what an electrolytes is, which is a substance that produces an electrically conducting solution when dissolved in a polar solvent, in this case water is the solvent. Based on the results of the experiment it is can be concluded that the sodium chloride solution best conduct electricity. This is due part by ions being separated into Na+ and Cl- ions from the original NaCl. In other words NaCl(s) becomes Na+ (aq) + Cl- (aq). In doing so allows electricity to flow in the solution. As for the pure/distilled water not conducting electricity it is because it is very filtered free of minerals. Essentially, distilled water lack ions to efficiently conduct electricity, this also applies to the pure substance of sodium chloride and sucrose which lack ions, atoms that have a net negative or positive charge. However, according the results the sucrose is slightly conductive, which may suggest a possible contamination in the solution. At the end it can be reasoned that because ions were made in the NaCl solution, ions contribute to the conductivity.

Based on the results salt water, sugar water, distilled water, and slightly isopropyl alcohol dissolved the Expo marker, while Oleic acid, slight Isopropyl alcohol dissolved the sharpie marker. All the solvents in the Expo trial have one thing in common: they are all polar and based on the saying "Like dissolves like" in this case Expo is polar therefore dissolved by polar solvents. This also applies to the sharpie, which is nonpolar because it does not dissolve in water which is polar. Especially Oleic acid, which is derived from oil and is polar. Therefore, it efficient dissolves the sharpie marker along with isopropyl alcohol which is also
