Q2)
Please provide the conductivity for 0.1M NaCl: [a] microsiemen/cm
Q3)
Would you expect the Group A compounds to partially dissociate, completely dissociate, or not dissociate at all? USE YOUR DATA to explain your choice
Q4)
Classify each chemical in Group B as a strong or weak electrolyte, and arrange them from strongest to weakest based on their conductivity values.Please use the terms strongest, weakest, or weak only.
Acetic acid =
HCl =
phosphoric acid
Q5)
Are the conductivity values for the compounds in Group C higher than, equal to, or lower than the compounds in groups A and B? Please explain your rationale.
Q6)
Compare the conductivity values for tap water and distilled water. Which is higher? Please explain.
