In other words, neutrals indirectly feel magnetic forces due to the collisional coupling. However, as collision frequencies reduce—at lower densities or temperatures, for example—there can be some drift between species.

WebH2CO3 (aq) (T/F) Sodium Chloride (NaCl) is considered an electrolyte because it dissolved in water into positive and negative ions. True. (T/F) A concentrated solution of a non-electrolyte such as glucose can be made to conduct electricity. False. (T/F) A saline solution will not conduct an electric current. A saline solution is a salt solution. The partition coefficient, abbreviated P, is defined as a particular ratio of the concentrations of a solute between the two solvents (a biphase of liquid phases), specifically for un-ionized solutes, and the logarithm of the ratio is thus log P. When one of the solvents is water and the other is a non-polar solvent, then the log P value is a measure of lipophilicity or hydrophobicity. The defined precede…
