Question 1.
Define conductance in your own words.
Show hintHide hint
Think about how easily electricity flows through materials.
Question 2.
What is molar conductance?
Show hintHide hint
Consider how conductance is measured in relation to moles.
3Question 3.
What is the formula for conductance (G)?
- G = R
- G = 1/R
- G = R^2
Show hintHide hint
Remember what the relationship between conductance and resistance is.
4Question 4.
True or False: Strong electrolytes show decreased molar conductance with dilution.
- True
- False
Show hintHide hint
Reflect on how ion mobility changes with dilution for strong electrolytes.
Question 5.
A specific conductance (κ) of sodium chloride solution is measured at 0.1 S/m. What is the molar conductance (Λₘ) if the concentration is 0.5 M?
Show hintHide hint
Remember to plug the values into the formula correctly.
Question 6.
Given that the molar conductance of acetic acid increases sharply upon dilution, explain why this occurs.
Show hintHide hint
Consider how the equilibrium shifts in response to changing concentrations.
