- Indicate the variation in conductivity with concentration in solutions of strong electrolytes and weak electrolytes.arrow_forwardThe molar conductivity of a very dilute solution of NaCl has been determined. If it is diluted to one-fourth of the initial concentration, qualitatively explain how the molar conductivity of the new solution will compare with the first.arrow_forwardWhat does the phrase mean, if instead of 1 Faraday of electricity, Q coulombs (Q/F Faradays) pass through?arrow_forward
- What characteristics should an interface that forms an electrode have?arrow_forwardFor a weak acid AcH, calculate the dissociated fraction (alpha), if its concentration is 1.540 mol L-1 and the concentration [H+] is 5.01x10-4 mol L-1.arrow_forwardIf the molar conductivity at infinite dilution of HAC is A0 = 390.5 S cm² mol¹. Calculate the Arrhenius conductivity of a 9.3% by weight solution of HAc with a pH of 3.3. Data: molecular weight of HAC is 60.05 g/mol and the density of the solution is 1 g/cm³.arrow_forward

DATA: dielectric constant of the medium for the interfacial zone &r= lectric constant of the vacuum &0 = 8.85-10-12 F m-1 = 50, die-arrow_forward
- Describe a sequence of photophysical processes that can be followed by radiation adsorbed by a molecule in the ground state to give rise to phosphorescent emission.arrow_forwardState two similarities between fluorescence and phosphorescence.arrow_forwardState three photophysical processes that can be related to the effects of incident radiation on a molecule in its ground state. Consider that radiation can give rise to fluorescent emission, but not phosphorescent emission.arrow_forward
