Explain why the conductivity of 0.077 M Na2SO4(aq) is greater than that of 0.077 M KF(aq). a)Ion size can play a big part in electrical conductivity. Some or all of the ions in KF are much smaller than the ions in Na2SO4, thus the ions in Na2SO4 are better able to conduct the electricity. b)Electrolytes with a SO42- anion will always have a higher conductivity when compared to any other electrolyte. Thus the Na2SO4 will always have a higher conductivity than KF as long as they are at the same concentration. c)The total ion concentration of the Na2SO4 is greater than the KF. In addition,
Explain why the conductivity of 0.077 M Na2SO4(aq) is greater than that of 0.077 M KF(aq). a)Ion size can play a big part in electrical conductivity. Some or all of the ions in KF are much smaller than the ions in Na2SO4, thus the ions in Na2SO4 are better able to conduct the electricity. b)Electrolytes with a SO42- anion will always have a higher conductivity when compared to any other electrolyte. Thus the Na2SO4 will always have a higher conductivity than KF as long as they are at the same concentration. c)The total ion concentration of the Na2SO4 is greater than the KF. In addition, some or all of the ions in Na2SO4 have higher charge than those of KF. Both of these factors increase the conductivity of the Na2SO4 solution. d)Conductivity increases when electrolytes react with water. Na2SO4 reacts much more readily with the water than KF, thus the greater reactivity of Na2SO4 will lead to a much greater conductivity in solution. e)The KF is a weak electrolyte while the Na2SO4 is a strong electrolyte. Thus the Na2SO4 fully ionizes in solution and will have a higher conductivity than the KF. Explain why the BaSO4 in water mixture does not conduct electricity even though BaSO4 is an ionic compound. a)BaSO4 is insoluble in water. In addition, since it is ionic it still soaks up any electrical charge that tries to pass through the solution. Thus the overall solution does not conduct electricity. b)BaSO4 ions in solution are too large, and have too low of a charge to effectively conduct electricity. c)BaSO4 is insoluble in water, so it does not dissociate into ions. Without ions in solution, the solution will not conduct electricity. d)BaSO4 dissovles as a molecular compound. Without ions in solution, the solution will not conduct electricity. e)BaSO4 dissociates into ions in solution, but these ions do not conduct electricity.
