Question Description

Need help with my Chemistry question – Im studying for my class.

Q1)

Please complete the Table below by adding the digits only :

Table 1. Data Table for Conductivity Measurements

Group	Solution or Liquid	Conductivity (?S/cm)
A	0.05 M CaCl₂
A	0.05 M AlCl₃
A	0.05 M NaCl
B	0.05 M Acetic acid (HC₂H₃O₂)
B	0.05 M HCl
B	0.05 M Phosphoric acid (H₃PO₄)
C	0.05 M CH₃OH
C	0.05 M C₆H₁₂O₆ (glucose)
C	H₂O (distilled)
C	H₂O (tap)

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.
