- 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

- 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
