3- Which statement is correct about a strong
electrolyte?
A- Examples of strong electrolytes include CH3CO2H and
Na[CH3CO2].
B-The molar conductivity decreases significantly as the
concentration increases.
C-The molar conductivity at infinite dilution can be found by
extrapolation from a plot of molar conductivity against
concentration.
D-It is partially ionized in aqueous solution.
4-Which statement is incorrect about a weak
electrolyte?
A-The molar conductivity of a weak electrolyte remains
approximately constant as the concentration increases.
B-Acetic acid is an example of a weak electrolyte.
C-At infinite dilution, a weak electrolyte is taken to be fully
ionized.
D- A weak electrolyte is partially dissociated in aqueous
solution.
